HEF4538B-Q100  
Dual precision monostable multivibrator  
Rev. 1 — 28 February 2013  
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) and an active HIGH  
trigger/retrigger input (nB). It has an overriding active LOW direct reset input (nCD) and an  
output (nQ) together with its complement (nQ). There are also two pins for connecting the  
external timing components Cext and Rext. These pins, nREXT/CEXT, and nCEXT, are  
always connected to ground. Typical pulse width variation over the specified temperature  
range is 0.2 %.  
Either the positive or the negative edges of the input pulse can trigger the multivibrator.  
The trigger produces an accurate output pulse with a pulse width range of 10 s to infinity.  
The external timing components Cext and Rext determine the duration and accuracy of the  
output pulse. 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 Schmitt  
trigger action of the trigger inputs, 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.  
2. Features and benefits
