Texas Instruments Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders CD54AC157F3A

The CD54AC157F3A is a quadruple 2-line to 1-line data selector/multiplexer designed for operation within a supply voltage range of 1.5 V to 5.5 V. It features a common strobe input that, when activated, sets all outputs to low, while allowing the selection of a 4-bit word from one of two sources when the strobe is low. The device is capable of driving outputs with a current of ±24 mA, supporting a fanout of up to 15 F devices. It is built using a SCR-latchup-resistant CMOS process, providing enhanced reliability and balanced noise immunity at 30% of the supply voltage. The CD54AC157F3A also meets ESD protection standards, exceeding 2 kV per MIL-STD-883, Method 3015, making it suitable for applications requiring robust performance in challenging environments.
