Quad 2-Input Data Selectors/Multiplexer with 3-State Outputs

The SL74HC258 is identical in pinout to the LS/ALS258. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device selects a (4-bit) nibble from either the A or B inputs as determined by the Select input. The nibble i
