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 (RX)

and an external capacitor (CX) control the timing for

the circuit. Adjustment of RX and CX 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 RX and CX.

Leading-edge-triggering (+ TR) and trailing-edge-

triggering (â TR) inputs are provided for triggering

from either edge of an input pulse. An unused + TR

input should be tied to VSS. An unused â TR input

should be tied to VDD. 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 VDD. How-

ever, if an entire section of the 4098B is not used,

its RESET should be tied to VSS. See table I. In nor-

mal operation the circuit triggers (extends the output
