CD4528BM CD4528BC Dual Monostable Multivibrator
General Description
The CD4528B is a dual monostable multivibrator Each de-
vice is retriggerable and resettable Triggering can occur
from either the rising or falling edge of an input pulse result-
ing in an output pulse over a wide range of widths Pulse
duration and accuracy are determined by external timing
components Rx and Cx
Features
Y Wide supply voltage range
3 0V to 18V
Y Separate reset available
Y Quiescent current e 5 0 nA package (typ ) at 5 0 VDC
Y Diode protection on all inputs
Y Triggerable from leading or trailing edge pulse
Y Capable of driving two low-power TTL loads or one
low-power Schottky TTL load over the rated tempera-
ture range
