QUADRUPLE 2-LINE TO 1-LINE
DATA SELECTORS/MULTIPLEXERS
„ DESCRIPTION
The U74AHC158 is a quadruple 2-line to 1-line data
selector/multiplexer. When G is high, all outputs are high. When
G is low, a 4-bit word is selected from one of with two sources and
is routed to the four outputs. The device provides inverted 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
