description/ordering information
NC − No internal connection
These data selectors/multiplexers contain inverters and drivers to supply full data selection to the four output
gates. A separate strobe (G) input is provided. A 4-bit word is selected from one of two sources and is routed
to the four outputs. The ’HC157 devices present true data.

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 51-7.
