GENERAL DESCRIPTION

The 74LVC157 is a quad 2-input multiplexer designed

for 1.2V to 3.6V operating voltage. The inputs from

3.3V or 5V devices make this device can be used as a

translator in a mixed 3.3V and 5V system environment.

The enable input (E) is active low. When E is held high,

the 1Y to 4Y outputs are forced to low-state no matter

what the conditions of the inputs are. When pin E is

held low, four bits of data are selected from one of two

sources that are determined by the state of the

common data selection input (S), and are routed to the

four outputs. The four outputs present the true

(non-inverting) selected data. The S input can also be

used as function generator
