8 Detailed Description
8.1 Overview
The SNx4HC32 devices are quad 2-input OR gates. These devices are members of the High-Speed CMOS (HC)
logic family. The HC family of logic is optimized to operate with a 5-V supply, is low noise without characteristic
overshoot and undershoot, has low power consumption, small propagation delay, balanced propagation delay
and transition times, and operates over a wide temperature range.
