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 input...
