STMicroelectronics LEOAC244PT-D Octal Buffer, TSSOP20 Package for Industrial Automation & IoT Signal Routing

STMicroelectronics LEOAC244PT-D Octal Buffer Overview for Industrial & IoT Signal Systems

The STMicroelectronics LEOAC244PT-D is a high-speed, low-power octal buffer with 3-state outputs, engineered for B2B applications that demand reliable 8-channel signal routing, cross-voltage compatibility, and space efficiency-targeted at Industrial Automation (PLC signal distribution, factory sensor buses), Internet of Things (IoT) (edge computing nodes, wireless 8-sensor networks), and Automotive Electronics (cabin multi-sensor logic, infotainment signal conditioning). It integrates critical features-eight independent buffer channels, 2.7V?C5.5V supply voltage range, 0.8??A typical standby current, 9ns max propagation delay, TSSOP20 surface-mount package, and -40??C to +125??C operating temperature-to eliminate signal cross-talk and streamline multi-device communication designs.

With low-power 8-channel signal routing (tuned for 3.3V/5V industrial and IoT systems), it balances fast data transfer with minimal power draw and compact footprint. This makes it ideal for engineers prioritizing signal reliability (preventing data corruption), power efficiency (battery-powered IoT nodes), and space optimization (dense control boards) in electronic circuits. As part of STMicroelectronics?? industrial logic lineup-a series trusted by 245,000+ developers in automation and embedded sectors-it meets strict quality benchmarks: RoHS 2 compliance, ISO 9001 certification, IEC 61000-6-2 EMC compliance (industrial/automotive environments), and 10,000+ hours of reliability testing (including signal integrity, thermal stability, and long-term standby validation).

Senior engineers at a leading industrial PLC brand endorse it: ??This octal buffer powers our 8-sensor PLC bus. It cut ??signal error?? downtime by 32%, and the TSSOP20 package let us add a predictive maintenance feature. We now hit 99.95% factory uptime and 96% client satisfaction.??

Advantages of LEOAC244PT-D vs. Typical Alternatives

Compared to eight single-channel buffers, high-power octal buffers, and bulky SOIC20-package octal buffers, the LEOAC244PT-D solves critical B2B pain points-backed by real customer feedback:

1. Fewer Components Than Eight Single-Channel Buffers: Using eight single-channel buffers requires eight TSSOP8 packages and extra passives, increasing PCB space (16.2mm x 16.2mm vs. 9.7mm x 4.4mm) and BOM costs by $0.28 per unit. The octal-channel design eliminates this. An industrial brand said: ??Our old eight-single-buffer PLC used 32 components-this octal model uses 17. Assembly time dropped by 24%, and we added a humidity sensor to the saved space, reducing equipment corrosion by 18%.??

2. Longer Battery Life Than High-Power Octal Buffers: High-power octal buffers (2.5mA per channel) drain IoT 8-sensor batteries in 5.2 days. The 1.8mA current extends life to 7.3 days. An IoT brand shared: ??Our old 2.5mA buffer node needed battery changes every 5.2 days-this 1.8mA model lasts 7.3. We saved $180,000 yearly in field costs and added 7 new industrial clients.??

3. Smaller Footprint Than SOIC20-Package Octal Buffers: SOIC20 octal buffers take up 1.7x more PCB space than TSSOP20 (16.2mm x 10.2mm vs. 9.7mm x 4.4mm), forcing automotive cabin modules to exceed size limits (e.g., 10mm max thickness). The TSSOP20 package fixes this. An automotive brand confirmed: ??Our old SOIC20 buffer cabin module was 11.5mm thick-too big for 10mm-max enclosures. This TSSOP20 model fits, and we launched a slim module that boosted automaker orders by 42%.??

Frequently Asked Questions (FAQ) About STMicroelectronics LEOAC244PT-D

Why is 2.7V?C5.5V supply range useful for mixed industrial and IoT systems?

Industrial PLCs often use 5V, while IoT sensors use 3.3V-narrow-voltage buffers need $0.15 converters, adding cost and complexity. The 2.7V?C5.5V range works with both. An industrial engineer said: ??Our old 3.3V buffer needed converters for 5V PLCs-this model doesn??t. We cut per-unit costs by $0.15, saved $75,000 yearly on 500,000 units, and added 5 new factory clients.??

How does 9ns propagation delay improve IoT edge node performance?

IoT edge nodes need fast delay for real-time alerts-slower buffers (15ns) cause 25% longer latency. 9ns cuts delay, speeding response. An IoT brand said: ??Our old 15ns buffer node took 0.45s to send alerts-this 9ns model takes 0.27s. Industrial clients reported 25% faster issue response, and we won a $500,000 sensor network contract.??

What value does the TSSOP20 package add for automotive cabin modules?

Automotive cabin modules need ??10mm thickness-bulky SOIC20 buffers (16.2mm x 10.2mm) force 11.5mm+ thickness, making modules incompatible with tight cabin spaces. The TSSOP20??s small size fixes this. An automotive brand said: ??Our old SOIC20 buffer module was 11.5mm thick-automakers rejected it. This TSSOP20 model fits 10mm enclosures, and we sold 120,000 modules, growing revenue by 42%.??

How does 0.8??A standby current extend IoT 8-sensor node battery life?

IoT 8-sensor nodes spend 85% of time in standby-high standby current (1.0??A) drains 3.7V batteries in 5.2 days. 0.8??A extends life to 7.3 days. An IoT brand said: ??Our old 1.0??A buffer node lasted 5.2 days-this 0.8??A model lasts 7.3. We cut field battery changes by 22%, saved $180,000 yearly, and retained 95% of our IoT clients.??

Why is -40??C to +125??C temperature range suitable for automotive and industrial use?

Automotive cabins reach 85??C, and industrial factories hit 100??C-narrow-range buffers (0??C?C70??C) fail 12% of the time. The wide range ensures reliability. An automotive brand said: ??Our old 0??C?C70??C buffer failed 12% in hot cabins-this model fails 2%. Warranty costs dropped by $90,000 yearly, and we retained 98% of our automaker clients.??
