HEF4538B-Q100
Dual precision monostable multivibrator
Rev. 4 — 4 March 2022
Product data sheet
1. General description
The HEF4538B-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.

[1] The typical values of the propagation delay and transition times are calculated from the extrapolation formulas shown (CL in pF).
[2] tt is the same as tTHL and tTLH
.
[3] The maximum permissible resistance REXT, which holds the specified accuracy of tW (nQ, nQ output), depends on the leakage current
of the capacitor CEXT and the leakage current of the HEF4538B.

damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
