- Wide operating voltage range: 2 V to 6 V
- Schmitt-trigger inputs allow for slow or noisy input signals
- Low power consumption
- Typical ICC of 100 nA
- Typical input leakage current of ±100 nA
- ±7.8-mA output drive at 6 V
- Extended ambient temperature range: –40°C to +125°C, TA
The SN74HCS157 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.
