74157 Quad 2-Line to 1-Line Data Selectors/Multiplexers

74HC157 is a high-speed multiplexer integrated circuit consisting of four 2-inputs digital multiplexers inside the chip. It is pin-compatible with Low-power Schottky TTL. It has two control inputs namely enable and select input. Additionally, it has two groups of registers. The select input determines the register from which the data comes. Its operation is specified over a temperature range of -55 C to 125 C.

Features:

• Quad multiplexer IC with a voltage range of 2V to 6V.
• Displays outputs in the non-inverted form.
• It has buffered inputs and outputs.
• The capability of driving 10 LS-TTL loads.
• The input voltage range is 1.35V to 3.15V.
• The outputs are directly Interfaced with CMOS, NMOS, and TTL.
• It is compatible with TTL/CMOS Input Logic.
• The maximum propagation delay is 25ns at Vcc = 4.5V.
