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. FEATURES * Non-inverting data path * 3-state outputs for bus interface * and multiplex expansion * Common select inputs * Separate output enable inputs * Output capability: bus driver * ICC category: MSI 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) GENERAL DESCRIPTION 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. 7A.
