balanced noise immunity at 30% of the supply
voltage
• Speed of bipolar F, AS, and S, with significantly
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.
