DESCRIPTION
The HCF4098B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4098B dual precision monostable
multivibrator provides stable retriggerable/
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
PIN CONNECTION
wide range of output pulse widths from the Q and
Q terminals. The time delay from trigger input to
output transition (trigger propagation delay) and
the time delay from reset input to output transition
(reset propagation delay) and the time delay from
reset input to output transition (reset propagation
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 provided
for immediate termination of the output pulse or to
prevent output pulses when power is turned on.
