SNx4HC157 Quadruple 2-Line to 1-Line Data Selectors/Multiplexers

1 Features

• Wide operating voltage range of 2V to 6V

• Outputs can drive up to 15 LSTTL loads

• Low power consumption, 80µA max ICC

• Typical tpd = 11ns

• ±6mA output drive at 5V

• Low input current of 1µA max

2 Description

The SNx4HC157 contains four data selectors/

multiplexers to select one of two data sources. All

channels are controlled by the same address select

(A/B) input, and strobe (G) input. A high level at the

strobe terminal forces all outputs low.
