This device contains two independent D-type negative-edge-triggered flip-flops. All inputs include Schmitt-triggers, allowing for slow or noisy input signals. A low level at the preset (PRE) input sets the output high. A low level at the clear (CLR) input resets the output low. Preset and clear functions are asynchronous and not dependent on the levels of the other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time requirements is transferred to the outputs (Q, Q) on the negative-going edge of the clock (CLK) pulse. Following the hold-time interval, data at the data (D) input can be changed without affecting the levels at the outputs (Q, Q).

參考設計

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。
