74HC253; 74HCT253 Dual 4-input multiplexer; 3-state Rev. 9 — 20 October 2022 Product data sheet 1. General description The 74HC253; 74HCT253 is a dual 4-bit multiplexer, each with four binary inputs (nI0 to nI3), an output enable input (nOE) and shared select inputs (S0 and S1). One of the four binary inputs is selected by the select inputs and routed to the output nY. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of cu.

They are specified in compliance with JEDEC standard no. 7A. 74HC/HCT253 The 74HC/HCT253 have two identical 4-input multiplexers with 3-state outputs which select two bits from four sources selected by common data select inputs (S0, S1). When the individual output enable (1OE, 2OE) inputs of the 4-input multiplexers are HIGH, the outputs are forced to the high impedance OFF-state. The “253” is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels applied to S0 and S1. The logic equations for the outputs are: 1Y = 1OE(1l0.S1.S0+1I1.S1.S0+1I2.S1.S0+1I3.S1.S0) 2Y = 2OE(2l0.S1.S0+2I1.S1.S0+2I2.S1.S0+2I3.S1.S0) APPLICATIONS • Data selectors •.
