1. General description

The HEF4538B is a dual retriggerable-resettable monostable multivibrator. Each multivibrator has

an active LOW trigger/retrigger input (nA), an active HIGH trigger/retrigger input (nB), an overriding

active LOW direct reset input (nCD), an output (nQ) and its complement (nQ), and two pins

(nREXT/CEXT, and nCEXT, always connected to ground) for connecting the external timing

components CEXT and REXT. Typical pulse width variation over the specified temperature range is

±0.2 .

The multivibrator may be triggered by either the positive or the negative edges of the input pulse

and will produce an accurate output pulse with a pulse width range of 10 μs to infinity. The duration

and accuracy of the output pulse are determined by the external timing components CEXT and

REXT. The output pulse width (tW) is equal to REXT × CEXT. The linear design techniques in

LOCMOS (Local Oxide CMOS) guarantee precise control of the output pulse width. A LOW level at

nCD terminates the output pulse immediately. The trigger inputs’ Schmitt trigger action makes the

circuit highly tolerant of slower rise and fall times.

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually

ground). Unused inputs must be connected to VDD, VSS, or another input.

2. Features and benefits
