MC14528BD

Multivibrators Overview

The MC14528BD is a dual, retriggerable, resettable monostable multivibrator manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports ambient temperatures from -55°C to +125°C. The device features diode protection on all inputs and can trigger from either the leading or trailing edge of an input pulse. It is capable of driving two low-power TTL loads or one low-power Schottky TTL load. The output pulse width is determined by external timing components CX and RX.

Multivibrators Feature Summary

• Dual independent monostable circuits with separate reset functionality
• Retriggerable operation triggered by either rising or falling edges
• Input diode protection for high static voltage safeguarding
• CMOS technology compatible with standard TTL logic loads

Multivibrators Applications

• Pulse generation and shaping in digital systems
• Timing delay circuits requiring retriggerable behavior
• Debounce applications for mechanical switches
• Clock frequency division using monostable configurations

Multivibrators Procurement Notes

Verify the specific package suffix 'D' corresponds to the SOIC-16 configuration required for your PCB layout. Confirm that the design utilizes external timing components RX and CX suitable for the desired pulse width, as internal timing is not provided. Ensure input lines are tied to appropriate logic levels when unused to prevent floating states.

Multivibrators Selection Notes

Select this component for designs requiring dual monostable functions in a single package. Consider the MC14538 if pulse widths exceeding 10 microseconds are necessary, as it offers pin-for-pin compatibility with extended timing capabilities. Evaluate the operating temperature range and supply voltage requirements against the specified 3V to 18V limits.

Multivibrators Part Context

This part belongs to the MC14528B series of CMOS logic devices. It is designed for general-purpose timing applications where retriggerability is essential. The device is part of the broader 4000/14000/40000 series family, ensuring compatibility with other standard CMOS logic components in mixed-logic designs.

Multivibrators Replacement Considerations

MC14528BDG is a direct replacement offering identical functionality in the same SOIC-16 package. For applications requiring longer pulse widths, the MC14538 serves as a pin-compatible alternative with enhanced timing characteristics.
