The SN74HCT32D is a Quad 2-Input Logic Gates IC manufactured by Texas Instruments. It consists of four 2-input OR gates, each of which provides the standard 2-input OR function. This IC operates from a single power supply of either 2.7-5.5V. Outputs are capable of sinking up to 32mA, and the maximum capacity of their output currents is up to 64mA. It is a surface mount IC with a small footprint and has a propagation delay time of 10ns. The IC is designed to meet the requirements of the MIL-STD-883. It is widely used in various applications such as power monitoring, industrial controllers, and digital logic circuits.
