description/ordering information

The ’LV157A devices are quadruple 2-line to

1-line data selectors/multiplexers designed for

2-V to 5.5-V V

operation.

These devices 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 ’LV157A devices

present true data.
