CD4528BC Dual Monostable Multivibrator
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 p ulse over a wide range of wi dths.
Pulse duration and accurac y are determined by external
timing components Rx and Cx.
Features
■ Wide supply voltage range: 3.0V to 18V
■ Separate reset available
■ Quiescent current
= 5.0 nA/package (typ.) at 5.0 V
DC
■ Diode protection on all inputs
■ Triggerable from leading or trailing edge pulse
■ Capable of driving two low- powe r TTL loa ds or one low -
power Schottky TTL load over the rated temperature
range
Ordering Code:
Devices also availab le in Tape and Reel. Specify by appending th e s uffix let t er “X” to the ordering code.

(Note 2)
Note 1: “Absolute Maximum Ratings” are those values bey ond which the
safety of the device cannot be guaranteed. Except for “Operating Temperature Range”, they are not m eant to i mply th at the devices shou ld be op erated at these limits. The table of “Electrical Characteristics” provides
conditions for actual device operation.
