U74AHC158
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.
CMOS IC
FEATURES
* Wide supply voltage range from 2V to 5.5V
* Max t
pd
of 4.1ns from A or B to Y at 5V, C
L
=15pF
* Low power consumption, I
CC
= 4
μA
(Max.) at 5.5V
* ±8 mA output driver at 5V

Note: 1.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
