Quad 2-Input Data Selector/Multiplexer With 3-State OutputsThe IN74ACT257 is identical in pinout to the LS/ALS257,
HC/HCT257. The IN74ACT257 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
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 high-impedance state. By Integral Corp.
