1. General description
2. Features and benefits
3. Applications
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 C
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 s to
infinity. The duration and accuracy of the output pulse are determined by the external
timing components C
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 V
(usually ground). Unused inputs must be connected to V
also suitable for use over the industrial (40 C to +85 C) and automotive (40 C to
+125 C) temperature ranges.
