CD74HC4538 高速 CMOS 逻辑双路可重触发精密单稳多频振荡器

The ’HC4538 and ’HCT4538 are dual retriggerable/resettable monostable precision multivibrators for fixed voltage timing applications. An external resistor (RX) and an external capacitor (CX) control the timing and the accuracy for the circuit. Adjustment of RX and CX provides a wide range of output pulse widths from the Q and Q\ terminals. The propagation delay from trigger input-to-output transition and the propagation delay from reset input-to-output transition are independent of RX and CX.

Leading-edge triggering (A) and trailing edge triggering (B)\ inputs are provided for triggering from either edge of the input pulse. An unused "A" input should be tied to GND and an unused B\ should be tied to VCC
