DESCRIPTION
The
HCC4098B
(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
dual monostable multivibrator provides stable retrig-
gerable/resettable one-shot operation for any fixed-
voltage timing application. An external resistor (R
X
)
and an external capacitor (C
X
) control the timing for
the circuit. Adjustment of R
X
and C
X
provides a wide
range of output pulse widths from the Q and Q ter-
minals. The time delay from trigger input to output
transition (trigger propagation delay) and the time
delay from reset input to output transition (reset pro-
pagation delay) are independent of R
X
and C
X
.
Leading-edge-triggering (+ TR) and trailing-edge-
triggering (– TR) inputs are provided for triggering
from either edge of an input pulse. An unused + TR
input should be tied to V
SS
. An unused – TR input
should be tied to V
DD
. A RESET (on low level) is pro-
vided for immediate termination of the output pulse
or to prevent output pulses when power is turned on.
An unused RESET input should be tied to V
DD
. How-
ever, if an entire section of the
4098B
is not used,
its RESET should be tied to V
SS
. See table I. In nor-
mal operation the circuit triggers (extends the output

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) is used. The time
period (T) for this multivibrator can be approximated

Notes
: 1. A Refriggerable one-shot multivibrator has an output pulse width which is extended one full time period (T
X
) after application of the
last trigger pulse.
2. A non-refriggerable one-shot multivibrator has a time period T
X
referenced from the application of the first trigger pulse.
