74LS153 Dual 4 to 1 Selector/Multiplexer

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.74LS153 monolithic, data selectors/multiplexers contain inverters and drivers to supply fully com- elementary, on-chip, binary decoding data selection to the AND-OR gates. Separate strobe inputs are provided for each of the two four-line sections.

74LS153 Features

• Contains Two Multiplexers To Select Data Inputs Based on Data Select Inputs
• Performs Parallel to Serial Conversion
• Low Power
• Operating Temperature up to 70°C
• Standard TTL Switching Voltages
