HD74HC257FPEL

Manufacturer Part Number
HD74HC257FPEL
Description
Manufacturer
Renesas Electronics Corporation.
Datasheet
HD74HC257
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 output control line is low, the select input chooses whether the A or B input is
used.
