MC74LCX32DTR2 Description

The MC74LCX32DTR2 from onsemi is a quad 2-input OR gate IC designed for low-voltage, high-speed digital logic applications. Part of the 74LCX series, it operates within a 2V to 3.6V supply range, making it ideal for mixed-voltage systems. With a max propagation delay of 5.5ns @ 3.3V, 50pF, it ensures efficient signal processing in high-performance circuits. The device features 4 independent OR gates, each with 2 inputs, and is packaged in a 14-pin TSSOP for surface-mount assembly. Its low quiescent current (10 µA max) and 24mA output drive capability enhance power efficiency while maintaining robust signal integrity.
