74HC257 Quad 2-Input Data Selector/Multiplexer

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 2-Input Data Selector/Multiplexer with 3-State Outputs High Performance Silicon Gate CMOS The MC74HC257 is identical in pinout to the LS257. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL 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 form when .
