DESCRIPTION
The 74LV153 is a low-voltage CMOS device that is pin and function compatible with 74HC/HCT153. The 74LV153 is a dual 4-input multiplexer which selects 2 bits of data from up to four sources selected by common data select inputs (S0, S1). The two 4-input multiplexer circuits have individual active LOW output enable inputs (1E, 2E) which can be used to strobe the outputs independently. The outputs (1Y, 2Y) are forced LOW when the corresponding output enable inputs are HIGH. The 74LV153 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=1E.(1l0.S1.S0+1l1.S1.S0+1l2.S1.S0+1l3.S1.S0) 2Y=2E.(2l0.S1.S……
