DESCRIPTION
TheHCC4098B(extended temperature range) and
HCF4098B (intermediate temperature range) are
monolithic integrated circuit, available in 16-lead
dual in-line dual in-line plastic or ceramic package
and plastic micropackage. The HCC/HCF4098B
dualmonostablemultivibrator providesstableretriggerable/resettable one-shot operation for any fixedvoltage timing application. An external resistor (RX)
and anexternal capacitor(CX) controlthetiming for
the circuit.Adjustment of RXand CXprovides a wide
range of outputpulse widths from theQ and Q terminals. The time delay from trigger input to output
transition (trigger propagation delay) and the time
delayfromreset input tooutput transition (reset propagation delay) are independent of RXand CX.
Leading-edge-triggering (+ TR) and trailing-edgetriggering (– TR) inputs are provided for triggering
from either edge of an input pulse. An unused + TR
input should be tied to VSS. An unused – TR input
shouldbetiedto VDD. ARESET(on lowlevel)isprovidedfor immediate termination of the outputpulse

AnunusedRESETinputshouldbetiedtoVDD.However, if an entire section of the 4098B is not used,
its RESETshouldbetied to VSS. See table I. Innormal operation the circuit triggers (extends theoutput

trigger pulse. For operation in the non-triggerable
mode, Q is connected to –TR when leading-edge
triggering (+ TR) is used or Q is connected to + TR
when trailing-edge triggering(–TR)isused.Thetime
period (T) for this multivibrator can be approximated
by TX=1/2 RXCXforCX≥ 0.01 µF.Timeperiods as
