Overview
The SN74LS279AN is an integrated circuit (IC) manufactured by Texas Instruments. It is a quadruple S-R latch IC, part of the 74LS family, which provides four independent S-R latch circuits in a single 16-pin package. Each latch has two external inputs (set and reset) and one output. The IC operates within a power supply voltage range of 4.75V to 5.25V and has a maximum propagation delay of 31 ns at 5V. This component is widely used in digital logic circuits for storing and manipulating binary data.
