SN74HCS151 8-to-1 Multiplexer with Schmitt-Trigger Inputs
1 Features
• Wide operating voltage range: 2 V to 6 V
• Schmitt-trigger inputs allow for slow or noisy input
signals
• Low power consumption
– Typical I
CC
of 100 nA
– Typical input leakage current of ±100 nA
• ±7.8-mA output drive at 6 V
• Extended ambient temperature range: –40°C to
+125°C, T
A
2 Applications
• Data selection
• Multiplexing
3 Description
The SN74HCS151 is a data selector/multiplexer
containing full binary decoding to select one of eight
data sources and complementary outputs. The strobe
(G) input must be at a low logic level to enable the
inputs. A high level at the strobe terminal forces the W
output high and the Y output low.

(1) Stresses beyond those listed under Absolute Maximum Rating may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under
Recommended Operating Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
(2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3) Guaranteed by design.
