Philips 74HCT253
The 74HC/HCT253 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 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.| Part No. | 74HCT253 |

GENERAL DESCRIPTION
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). 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 =...
