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
CC
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.
