1. General description
The 74LV153 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC153 and 74HCT153.
The 74LV153 provides 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 (1I0 S1 S0 + 1I1 S1 S0 + 1I2 S1 S0 + 1I3 S1 S0)
2Y = 2E (2I0 S1 S0 + 2I1 S1 S0 + 2I2 S1 S0 + 2I3 S1 S0)
