LEOAC32PT-D STMicroelectronics 4-Channel OR Gate IC — Mingjiada Electronics Specializes in Supply and Procurement

LEOAC32PT-D Product Overview

The LEOAC32PT-D is a high-performance, four-channel, two-input OR gate integrated circuit developed by STMicroelectronics, manufactured using the advanced 74AC series CMOS process. This device integrates four independent two-input OR gates into a compact 20-TSSOP package and operates over a wide voltage range of 2V to 6V, making it suitable for a wide variety of digital logic signal processing applications.

As an authentic ST product, the LEOAC32PT-D features excellent characteristics such as low quiescent current (typical value of 40 µA), high output drive capability (±24 mA), and an ultra-fast propagation delay of 9 ns (@4.5 V, 50 pF). With an operating temperature range spanning -40°C to +125°C, it meets the demands of industrial-grade applications.

Shenzhen Mingjiada Electronics Co., Ltd., as a professional distributor of electronic components, consistently stocks genuine LEOAC32PT-D units in stock. We also purchase this model and various other ST-branded logic devices and power management chips at competitive prices, providing customers with one-stop component supply and inventory optimization services.

Product Features

1. High-Speed CMOS Logic Performance

The LEOAC32PT-D is based on the 74AC series high-performance CMOS process. With a propagation delay as low as 9 ns under a 4.5 V supply voltage and a 50 pF load, it is suitable for high-speed digital signal processing systems.

2. Wide Voltage Compatibility

Supports a supply voltage range of 2 V to 6 V and is compatible with both 3.3 V and 5 V logic-level systems, greatly simplifying interface design for multi-voltage-domain systems.

3. High Output Drive Capability

With an output drive capability of ±24 mA, it can directly drive loads such as LED indicators or small relays, reducing the need for external driver circuits.

4. Ultra-Low Quiescent Power Consumption

With a maximum quiescent current of only 40 µA, it is ideal for battery-powered and low-power portable devices.

5. Wide Operating Temperature Range

An industrial-grade temperature range of -40°C to +125°C ensures stable operation in harsh environments.

6. Compact Package

The 20-TSSOP package is extremely compact (4.4 mm wide), making it suitable for high-density PCB layouts and effectively saving board space.

Typical Applications

Thanks to its outstanding performance parameters and high reliability, the LEOAC32PT-D is widely applicable in the following fields:

Industrial Control Systems: PLC logic control, sensor signal conditioning, and combinational decision-making

Automotive Electronics: Body control modules, logic signal processing for in-vehicle infotainment systems (must comply with relevant AEC-Q100 requirements)

Communication Equipment: Control logic and status signal processing in base stations, routers, and switches

Medical Devices: Low-power logic processing in portable monitoring equipment and diagnostic instruments

Consumer Electronics: Digital logic units for smart home devices, IoT gateways, and wearable devices
