74AHC257 74AHCT257 Quad 2-input multiplexer 3-state Rev. 02 9 May 2008 Product data sheet 1. General description The 74AHC257 74AHCT257 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specied in compliance with JEDEC standard No. 7-A. The 74AHC257 74AHCT257 has four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and are controlled by a common data select input (S). The data inputs from source 0 (1I0 to 4I0) are selected when input S is LOW and the data inputs from source 1 (1I1 to 4I1) are selected when input S is HIGH. Data appears at the outputs (1Y to 4Y) in true (non-inverting) form from the selected inputs. The 74AHC257 74AHCT257 is the logic implementation of a 4-pole 2-position switch, where the position of the switch is determined by the logic levels applied to input S. The outputs are forced to a high-impedance OFF-state when OE is HIGH. The logic equations for the outputs are: 1Y = OE (1I1 S + 1I0 S) 2Y = OE (2I1 S + 2I0 S) 3Y = OE (3I1 S + 3I0 S) 4Y = OE (4I1 S + 4I0 S) The 74AHC257 74AHCT257 is identical to the 74AHC258 74AHCT258, but has non-inverting (true) outputs. 2.
