SN74HC157N

XBLW SN74HC/HCT157 Quad 2-input Multiplexer General Description The SN74HC/HCT157 are quad 2-input multiplexers which select 4 bits of data from two sources under — — the control of a common data select input (S). The enable input (E) is active LOW. When E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions. Moving the data from two groups of registers to four common output buses is a common use of the SN74HC/HCT157. The state of the common data select input (S) determines the particular register from which the data comes. It can also be used as function generator. The device is useful for implementing highly irregular logic by generating any four of the 1 6 different functions of two variables with one variable common. The SN74HC/HCT157 is logic implementation of a 4-pole, 2-position switch, where the position of the switch is determined by the logic levels applied to S. The logic equations are: — — — — — — — — 1Y=E×(1I1×S+1I0×S) 2Y=E×(2I1×S+2I0×S) 3Y=E×(3I1×S+3I0×S) 4Y=E×(4I1×S+4I0×S) The SN74HC/HCT157 is identical to the SN74HC/HCT158 but has non-inverting (true) outputs.
