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.
