description
These quadruple 2-line to 1-line data
selectors/multiplexers are designed for 4.5-V to
5.5-V V

operation.
The ’AHCT158 devices feature a common 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 devices provide inverted
data.
The SN54AHCT158 is characterized for
operation over the full military temperature range
of –55°C to 125°C. The SN74AHCT158 is
characterized for operation from –40°C to 85°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.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.
