CD74HC4538-Q1 汽车类高速 CMOS 逻辑双路可重触发精密单稳多频振荡器
The CD74HC4538 is a dual retriggerable/resettable precision monostable multivibrator for fixed-voltage timing applications. An external resistor (RX) and external capacitor (CX) control the timing and 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 input should be tied to VCC. On power up, the IC is reset
