## Description

The Texas Instruments HCT32 is a high-speed CMOS logic integrated circuit containing four independent 2-input OR gates. It is designed to achieve operating speeds comparable to LSTTL gates while maintaining the low power consumption characteristic of standard CMOS circuits.

Key electrical specifications include a typical propagation delay of 7ns at VCC = 5V, CL = 15pF, and TA = 25°C. The HCT logic family operates from 4.5V to 5.5V and offers direct LSTTL input logic compatibility. Standard outputs can drive 10 LSTTL loads, while bus driver outputs can drive 15 LSTTL loads.

This device features a wide operating temperature range from -55°C to 125°C. It is available in a 14-lead SOIC surface mount package. The HCT32 is functionally pin compatible with the standard LS logic family, making it suitable for various digital logic applications where OR gate functionality is required.

Proper handling procedures for electrostatic discharge sensitive devices should be followed. The HCT32 provides significant power reduction compared to LSTTL logic ICs.
