Quad 2-Input Schmitt Trigger IC - 74HC132

The 74HC Series 74HC132 is a quad 2-input Schmitt trigger integrated circuit that is commonly used for signal conditioning and noise filtering. The Schmitt trigger input ensures that the IC's output switches cleanly and reliably in response to changes in the input signal.

The 74HC132 contains four independent gates each of which performs the logic NAND function. Each input has hysteresis which increases the noise immunity and transforms a slowly changing input signal to a fast-changing, jitter-free output.

1.What is a Schmitt trigger?

  • Schmitt triggers are electronic circuits that can transform a noisy or slowly changing input signal into a clean, well-defined output signal. It employs positive feedback to introduce hysteresis, which means that the output state is affected not only by the level of the input signal, but also by its history. This can aid in the removal of noise and other sources of signal distortion.

2.What is the typical voltage range for the inputs and outputs of the 74HC132?

  • The 74HC132 is intended to operate with a supply voltage of 2-6 volts and an input and output voltage range of 0-5 volts. These values, however, may differ depending on the specific conditions and applications in which the IC is used.
