CD4528BM/CD4528BC Dual Monostable Multivibrator
February 1988
CD4528BM/CD4528BC Dual Monostable Multivibrator
General Description
The CD4528B 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
Y
Wide supply voltage range 3.0V to 18V
Y
Separate reset available
Y
Quiescent currente5.0 nA/package (typ.) at 5.0 V
DC
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 temperature range
