The NXP PC74HCT32T is a high-speed Si-gate CMOS device that is pin compatible with low power Schottky TTL (LSTTL). It is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL, combined with the low power consumption of standard CMOS integrated circuits. This product is part of the 74HCT range, which is specified in compliance with JEDEC standard no. 7A.
Key Features
- Optimized for operation at 5V power supply, with a voltage range between 4.5V and 5.5V, making it suitable for interfacing with 5V logic levels in mixed-voltage systems.
- High noise immunity characteristic of CMOS technology ensures stable operation in noisy environments.
- Low power consumption is a hallmark of the device, with a typical ICC of 1 µA, making it ideal for power-sensitive applications.
- The device features a balanced propagation delay and transition times, providing reliable and fast operation suitable for high-speed data processing and communication systems.
- Output capability is standard, with the ability to drive 10 LSTTL loads, which allows for easy integration into existing digital systems.
- Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
