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

These analog multiplexers and 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 that, when high, disables all switches to their off state.

參考設計

TIDA-060014 — 用於 PLC 的 96 通道雙向數位輸入模組參考設計

此參考設計使用隔離式數位輸入接收器 ISO1212，實現 96 個隔離式數位輸入通道的精巧實作。此設計展現了 ISO1212 裝置的電流限制功能，其熱性能優於傳統光耦合器解決方案。此設計可讓具備多通道的數位輸入電路板變得更精巧，並降低電路板溫度（低於 50°C）。採用 ISO1212 裝置的多工器和解碼器可將微控制器的接腳數量從 96 降至 8。此設計已經過每通道 100kHz 輸入訊號 (200kbit) 的測試。該設計使用低於 7.3W 的輸入功率，可減少散熱。所有訊號的設計均符合 IEC6100-4 標準，可承受 ESD、EFT 及突波事件。
