INTEGRATED CIRCUITS DATA SHEET 74AHC257; 74AHCT257 Quad 2-input multiplexer; 3-state Product specification 2000 Apr 03 File under Integrated Circuits, IC06 Philips Semiconductors Product specification 74AHC257; Quad 2-input multiplexer; 3-state 74AHCT257 FEATURES data from two sources and are controlled by a common data select input (S). • ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V The data inputs from source 0 (1I0 to 4I0) are selected MM EIA/JESD22-A115-A exceeds 200 V when input S is LOW and the data inputs from source 1 CDM EIA/JESD22-C101 exceeds 1000 V (1I1 to 4I1) are selected when S is HIGH. Data appears at the outputs (1Y to 4Y) in true (non-inverting) form from the • Balanced propagation delays selected inputs. • All inputs have Schmitt-trigger actio
