CD4528BC
Dual Monostable Multivibrator
General Description
The CD4528BC is a dual monostable multivibrator. Each
device is retriggerable and resettable. Triggering can occur
from either the rising or falling edge of an input pulse,
resulting in an output pulse over a wide range of widths.
Pulse duration and accuracy are determined by external
timing components Rx and Cx.
Features
s Wide supply voltage range: 3.0V to 18V
s Separate reset available
s Quiescent current = 5.0 nA/package (typ.) at 5.0 VDC
s Diode protection on all inputs
s Triggerable from leading or trailing edge pulse
s Capable of driving two low-power TTL loads or one low-
power Schottky TTL load over the rated temperature
range
