74LS353-Dual 4-Bit Multiplexer I(Inv. Out)
Package SOIC Series 74LS
74LS353 overview
The 74LS series of integrated circuits (ICs) was one of the most popular logic families of transistor-transistor logic (TTL) logic chips. 74LS series is a bipolar, low-power Schottky IC. The 74LS353 is a Dual 4-Input Multiplexer with 3-state outputs. It can select two bits of data from four sources using common select inputs.
