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
