QUADRUPLE 2-LINE TO 1-LINE
DATA SELECTORS /
MULTIPLEXERS
„ DESCRIPTION
The U74AHC157 is a quadruple 2-line to 1-line data
selector/multiplexer. When G is high all outputs are low. When G is
low a 4-bit word is selected from one of two sources and is routed to
the four outputs. The device provides true data.
„ FEATURES
* Wide supply voltage range from 2V to 5.5V
* Max tPD of 4.1ns from A or B to Y at 5V, CL=15pF
* Low power consumption, ICC = 4 μA (MAX) at 5.5V
* ±8 mA output driver at 5V
