HC257

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

The SL74HC257 is identical in pinout to the LS/ALS257. 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

Quad. 2-to-1-line Data Selectors/Multiplexers(with noninverted 3-state outputs)

Description The large output drive capability coupled with the 3-state feature make this device ideal for interfacing with bus lines in a bus organized system. When the output control input line is taken high, the outputs of all four multiplexers are sent into a high impedance state. When the out
