IDT74LVC157A
EXTENDED COMMERCIAL TEMPERATURE RANGE
DESCRIPTION:
This quadruple 2-line to 1-line data selector/multiplexer is built using
advanced dual metal CMOS technology. The LVC157A features a common
strobe (
G
) input. When the strobe is high, all outputs are low. When the
strobe is low, a 4-bit word is selected fromone of two sources and is routed
to the four outputs. The device provides true data.
Inputs can be driven fromeither 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mxed 3.3V/5V supply system
The LVC157A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
