CD4528 Dual Monostable Multivibrator – Datasheet

4,972 views

The CD4528 is a part of the CD4000 IC series. CD4528 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. The CD4528 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL configurations. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers.

Monostable Multivibrator

A monostable multivibrator (MMV), often called a one-shot multivibrator, is a pulse generator circuit in which the duration of the pulse is determined by the R-C network, connected externally to the 555 timers. In such a vibrator, one state of output is stable while the other is quasi-stable (unstable). For auto-triggering of output from a quasi-stable state to a stable state, energy is stored by an externally connected capaci­tor to a reference level. The time taken in storage determines the pulse width.

CD4528 Key Features
