74HC4538; 74HCT4538  
Dual retriggerable precision monostable multivibrator  
Rev. 03 — 8 June 2009  
Product data sheet  
1. General description  
The 74HC4538; 74HCT4538 are high-speed Si-gate CMOS devices and are pin  
compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with  
JEDEC standard no. 7A.  
The 74HC4538; 74HCT4538 are dual retriggerable-resettable monostable multivibrators.  
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) 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. 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 on pins nA and nB makes the circuit highly tolerant of slower rise and fall times.  
2. Features  
I Tolerant of slow trigger rise and fall times  
I Separate reset inputs  
I Triggering from falling or rising edge  
I Multiple package options  
I ESD protection:  
N HBM JESD22-A114E exceeds 2000 V  
N MM JESD22-A115-A exceeds 200 V  
I Specified from 40 °C to +85 °C and from 40 °C to +125 °C
