Quad 2-Input Data Selector/Multiplexer with 3-State Outputs
High-Speed Silicon-Gate CMOS
The IN74AC257 is identical in pinout to the LS/ALS257, HC/HCT257. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
This device selects a (4-bit) nibble from either the A or B inputs as determined by the Select input. The nibble is presented at the outputs in noninverted from when the Output Enable pin is at a low level. A high level on the Output Enable pin switches the outputs into the high-impedance state.
? Outputs Directly Interface to CMOS, NMOS, and TTL
? Operating Voltage Range: 2.0 to 6.0 V
? Low Input Current: 1.0 μA; 0.1 μA @ 25°C
? High Noise Immunity Characteristic of CMOS Devices
? Output Source/Sink 24 mA
