DESCRIPTION
TheHCC4538B (extended temperature range) and
HCF4538B (intermediate temperature range) are
monolithic integrated circuit, available in 16-lead
dual in-line plastic or-ceramic package and plastic
micropackage.TheHCC/HCF4538Bdualprecision
monostable multivibrator provides stable retriggerable/resettable one-shot operation for any fixedvoltage timing application. An external resistor (RX)
andanexternalcapacitor(CX) controlthetimingand
accuracy for the circuit. Adjustment of RXand C
provides a wide range of output pulse widths from
the Q and Q terminals. The timedelay from trigger
inputtooutput transition (trigger propagation delay)
and the time delayfrom reset input to output transition(resetpropagation delay)are independent ofR
and CX. Precision control of output pulse widths is
achieved through linear CMOS techniques. Leading-edge-triggering (+TR)and trailing-edge-triggering (– TR) inputs are provided for triggering from
eitheredge of aninput pulse. Anunused+TR input
shouldbe tiedto VSS. An unused– TRinput should
be tied to VDD. A RESET (on low level) is provided
for immediate termination of the output pulse or to

can be calculated by : T = RXCX. The min. value of
externalresistance,RX,is4KΩ. The max. and min.
values of external capacitance, CX, are100µF and
5nF,respectively.
