IN74AC257 Datasheet | IK Semiconductor

TECHNICAL DATA 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 patible with standard CMOS outputs; with pullup resistors, they are patible 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 highimpedance state. - Outputs Directly Interface to CMOS, NMOS, and TTL - Operating Voltage Range: 2.0 to 6.0 V -...
