CD4528BCN

Multivibrators Overview

The CD4528BC is a dual monostable multivibrator manufactured by Fairchild Semiconductor. It features two independent retriggerable and resettable circuits capable of generating output pulses with widths determined by external timing components Rx and Cx. The device supports triggering from either the rising or falling edge of an input pulse. It operates within a wide supply voltage range of 3.0V to 18V, with a typical quiescent current of 5.0 nA/package at 5.0 VDC. Inputs include diode protection, and outputs can drive two low-power TTL loads or one low-power Schottky TTL load.

Multivibrators Feature Summary

• Dual independent monostable multivibrator circuits with separate reset functionality

Multivibrators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches requirements: N16E (16-Lead Plastic Dual-In-Line) or M16A (16-Lead Small Outline Integrated Circuit). Check datasheet revisions and compliance documentation for specific manufacturing lot requirements.

Multivibrators Selection Notes

Select based on required operating temperature range of -55°C to +125°C and supply voltage compatibility between 3V and 15V. Ensure external timing components Rx and Cx are chosen to achieve desired pulse widths within specified accuracy limits. Consider package selection based on board space constraints and thermal dissipation needs.

Multivibrators Part Context

Multivibrators FAQ

Can the CD4528BC be triggered by both rising and falling edges?

Yes, the device allows triggering from either the rising or falling edge of an input pulse.

What determines the output pulse width?
