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.
