reduced power consumption

• Balanced propagation delay

• ±24mA output drive current- fanout to 15F devices

2 Applications

• Data selection

• Multiplexing

3 Description

These quadruple 2-line to 1-line data selectors/

multiplexers are designed for 1.5V to 5.5V VCC

operation

The ’AC157 devices feature 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 devices provide true data.
