The TMUX1219 is a general purpose complementary metal-oxide semiconductor (CMOS) single-pole double-throw (SPDT) switch. The TMUX1219 switches between two source inputs based on the state of the SEL pin. Wide operating supply of 1.08 V to 5.5 V allows for use in a broad array of applications from personal electronics to building automation. The device supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from GND to VDD. A low supply current of 4 nA enables use in portable applications.
All logic inputs have 1.8 V logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range. Fail-Safe Logic circuitry allows voltages on the control pins to be applied before the supply pin, protecting the device from potential damage.

TIDA-050058 — 固態繼電器的零交叉切換參考設計
此參考設計展示如何以固態繼電器實現零交叉切換 (ZCS)。參考設計配備 TPSI3050-Q1 隔離開關驅動器。TPSI3050-Q1 裝置整合了層壓變壓器，在將訊號和電源傳輸至二次側時實現隔離。如此就不需要任何隔離偏壓電源。此外，TPSI3050-Q1 裝置可爲位於高電壓 (HV) 側的外部電路提供輔助電流 (IAUX)。ZCS 會在維持低電壓 (LV) 和 HV 側之間的訊號隔離情況下完成。此參考設計實現了具有 110-VRMS、60-Hz AC 電源的 12-V、200-µs 延遲 ZCS。
