description/ordering informationThe 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. Unused resets and sections must be terminated. In normal operation, the circuit
retriggers on the application of each new trigger pulse. To operate in the nontriggerable mode, Q is connected
to B when leading-edge triggering (A) is used, or Q is connected to A when trailing-edge triggering (B) is used.
The period (τ) can be calculated from τ = (0.7) RX, CX; RMIN is 5 kΩ. CMIN is 0 pF.
