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
