74279 Quad Set-Reset Latch Logic IC

The 74279 is a TTL logic IC that integrates four independent set-reset latches in a single package.
It provides asynchronous data storage using separate set and reset control inputs.
The device operates from a single 5 V supply and is compatible with standard TTL logic levels.
Each latch maintains its output state until an opposing control input is asserted.
Typical applications include state storage, control logic, signal debouncing, and digital sequencing circuits.
