General Description
IDT74LVC157A General 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 from one of two sources and is routed to the four outputs. The device provides true data.
Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 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.
