SN74HCS157数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

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.

• 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
