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.
