The CD74HC4067 and CD74HCT4067 devices are digitally controlled analog switches that utilize silicon-gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.

These analog multiplexers/demultiplexers control analog voltages that may vary across the voltage supply range. They are bidirectional switches thus allowing any analog input to be used as an output and vice-versa. The switches have low "on" resistance and low "off" leakages. In addition, these devices have an enable control which when high will disable all switches to their "off" state.

TIDA-060014 — 适用于 PLC 的 96 通道双向数字输入模块参考设计

此参考设计利用 ISO1212（一款隔离式数字输入接收器）实现了一款紧凑的 96 通道隔离数字输入模块。该设计展示了 ISO1212 器件的电流限制功能，其热性能优于传统的光耦合器解决方案。此设计让具有多个通道的数字输入电路板更加紧凑，并可降低电路板温度（低于 50°C）。具有 ISO1212 器件的多路复用器和解码器可将微控制器的引脚数量由 96 个减少至 8 个。该设计经过测试，每个通道可支持 100kHz 输入信号 (200kbit)。该设计的输入功率低于 7.3W，因而热耗散更少。所有信号均可承受符合 IEC6100-4 标准的 ESD、EFT 和浪涌事件。
