Product Description

The SN74HC132 features Schmitt-trigger inputs that make it immune to slower input rise and fall times, which helps in providing a cleaner, jitter-free output signal. These Schmitt-trigger inputs also enable the device to be used for transforming slowly changing input signals into sharply defined jitter-free output signals, enhancing its utility in applications requiring such characteristics.

Each circuit functions as a two-input NAND gate with Schmitt-trigger inputs, but because of the Schmitt action, they have different input threshold levels for positive-going (V_T+) and negative-going (V_T-) signals. This hysteresis between the positive-going and negative-going input thresholds (typically 0.9 V at VCC = 4.5 V) provides noise immunity and transforms a slowly changing input signal to a fast changing, jitter-free output.

With its robust design and ease of use, the SN74HC132 is an excellent choice for designers looking for a reliable logic solution that can handle the demands of complex digital systems.
