General Description

/ordering information 1Q 6 1Q 7 11 2B 10 2Q The CD74HC4538 is a dual retriggerable/resettable GND 8 9 2Q 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.
