description
The F158A is a quadruple 2-input data
selector/multiplexer featuring a direct strobe (G)
input. When the strobe is high, all outputs are high.
When the strobe is low, a 4-bit word is selected
from one of two sources and is routed to the four
outputs. The F158A provides inverted data.
The SN54F158A is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The SN74F158A is characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage rating may be exceeded provided that the input current rating is observed.
