STMicroelectronics M74HCT132B1R Quad Schmitt Trigger NAND Gate

The M74HCT132B1R is a high-speed Si-gate CMOS device from STMicroelectronics that provides the electrical characteristics of high-speed TTL combined with the very low power consumption of CMOS technology. This integrated circuit is designed specifically as a quad 2-input NAND gate with Schmitt trigger action on all inputs. The Schmitt trigger feature allows for a smoother transition and better noise immunity, making it an ideal choice for applications that require a clean switch without the interference of electrical noise.

Each gate in the M74HCT132B1R operates with inputs that switch at different points for positive and negative-going transitions. This hysteresis between the positive-going input threshold (V<sub>T+) and the negative-going input threshold (V<sub>T-) is determined by Schmitt trigger action and is particularly useful for transforming slowly changing input signals into sharply defined jitter-free output signals, thereby enhancing the device's capability to transform noisy signals into a clean digital output.

The device is compatible with LSTTL outputs, and this capability allows the M74HCT132B1R to be used in mixed-technology systems. It operates over a wide range of supply voltages from 4.5V to 5.5V, making it versatile for use in various applications. The M74HCT132B1R also features low input current, further reducing the power consumption and making it suitable for battery-operated and power-sensitive designs.

Furthermore, the M74HCT132B1R is offered in a DIP14 package, ensuring ease of integration into a wide array of design layouts. Its robustness is underscored by the fact that it can tolerate inputs up to 15V, regardless of the operating voltage, providing a measure of protection against higher voltage spikes in the electrical environment.

Whether you are designing consumer electronics, communication devices, or complex computing systems, the M74HCT132B1R from STMicroelectronics is a reliable and efficient choice for ensuring signal integrity through noisy environments.
