SN74HC257DR TI Signal Switches, Multiplexers, Decoders

The SN74HC257 is a quadruple 2-line to 1-line data selector/multiplexer with 3-state outputs, operating from a 2-V to 6-V supply . It features four independent 2:1 multiplexers with a common select (S) input and independent output-enable (OE) inputs. The device provides balanced propagation delays, low power consumption (80-µA max ICC), and high output drive (7.8-mA sink/source). Packaged in a 16-pin SOIC (DR), it is ideal for data routing and bus isolation in digital systems. Applications include microprocessor data selection, memory multiplexing, and signal gating in industrial controls and consumer electronics requiring high-speed CMOS performance.
