TECHNICAL DATA IN74ACT257 Quad 2-Input Data Selector/Multiplexer with 3-State Outputs High-Speed Silicon-Gate CMOS The 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.
