SN74HC132DR – TEXAS INSTRUMENTS

The SN74HC132DR is a quad 2-input OR gate in a space-saving SOIC-14 package. It’s a high-speed CMOS device operating from a wide 2V to 6V supply voltage range (V_CC), offering significant design flexibility. This part features Schmitt-trigger input buffers, providing superior noise immunity compared to standard OR gates. The typical propagation delay is a fast 8ns (V_CC = 5V, T_A = 25°C), making it suitable for high-frequency applications. Each gate’s output can source or sink up to 10mA, enabling it to drive multiple subsequent logic circuits._x000D_

The SN74HC132DR excels in applications requiring robust OR logic with noise tolerance. Common use cases include data signal conditioning, simple combinational logic designs within microcontrollers or FPGAs, and buffering signals in noisy environments. Its low power consumption (typically <1µA quiescent current) makes it ideal for battery-powered systems. The Schmitt-trigger inputs effectively eliminate spurious transitions caused by slow rise/fall times or noise spikes, contributing to improved system reliability. Designers should note the maximum output voltage swing is typically V_CC-0.5V. Its compact SOIC-14 footprint simplifies PCB layout and reduces component count.
