74HC4538-Q100  
Dual retriggerable precision monostable multivibrator  
Rev. 3 — 17 March 2017  
Product data sheet  
1 General description  
The 74HC4538-Q100 is a dual retriggerable-resettable monostable multivibrator. Each  
multivibrator has two trigger/retrigger inputs (nA and nB), a direct reset input (nCD),  
two complementary outputs (nQ and nQ), and two pins (nREXT/CEXT and nCEXT)  
for connecting the external timing components CEXT and REXT. Typical pulse width  
variation over temperature range is ± 0.2 %. The device may be triggered by either the  
positive or the negative edges of the input pulse. 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 0.7 × REXT × CEXT. The linear design techniques guarantee  
precise control of the output pulse width. A LOW level at nCD terminates the output pulse  
immediately. Schmitt-trigger action in the trigger inputs makes the circuit highly tolerant  
to slower rise and fall times. Inputs include clamp diodes. This enables the use of current  
limiting resistors to interface inputs to voltages in excess of VCC  
.
This product has been qualified to the Automotive Electronics Council (AEC) standard  
Q100 (Grade 1) and is suitable for use in automotive applications.
