STMicroelectronics M74HC132BI Quad 2-Input NAND Schmitt Trigger

The M74HC132BI is a high-speed CMOS Quad 2-Input NAND Schmitt Trigger manufactured by STMicroelectronics, designed to operate with a power supply ranging from 2V to 6V. This integrated circuit (IC) is part of the HC family, which is well-known for combining the high noise immunity of CMOS with the speed of TTL circuits. The M74HC132BI is specifically created to provide robust hysteresis characteristics, making it an ideal choice for applications that require noise-filtering and signal conditioning.

Each of the four independent NAND gates in the M74HC132BI features a Schmitt trigger action on both inputs, which allows the circuit to transform a noisy input signal into a clean digital output signal. The hysteresis provided by the Schmitt trigger enhances noise immunity and prevents unwanted oscillations, making this IC highly suitable for interfacing with slow-rising or falling input signals.

The M74HC132BI is available in a variety of packages, including DIP, SOIC, and TSSOP, providing flexibility for different types of circuit board layouts. Its low power consumption and high noise immunity make it a versatile component for a wide array of electronic applications, from consumer electronics to industrial control systems.

Key features of the M74HC132BI include:

• High-speed operation: t<sub>PD = 15 ns (typ) at V<sub>CC = 6V
