CD4528BC Dual Monostable Multivibrator
General Description
The CD4528BC 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
s Wide supply voltage range: 3.
0V to 18V s Separate reset available s Quiescent current = 5.
0 nA/package (typ.
) at 5.
0 VDC s Diode protection on all inputs s Triggerable from leading or trailing edge pulse s Capable of driving two low-power TTL loads or one low-
power Schottky TTL load over the rated temperature range
