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

Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation
Note 2 VSS e 0V unless otherwise specified
Note 3 IOH and IOL are tested one output at a time
