A6818EEP-T

Overview

The A6818EEP-T is a 32-bit serial input latched source driver manufactured by Allegro MicroSystems. It integrates a CMOS shift register, data latches, and control circuitry with bipolar sourcing outputs and PNP active pull-downs. The device operates in a 44-pin LPCC package and supports a 5V logic supply. Designed primarily for vacuum-fluorescent displays, it features high-speed data storage and controlled output slew rates.

Feature Summary

Combines 32-bit CMOS shift register with bipolar sourcing outputs and PNP active pull-downs
Features controlled output slew rate and high-speed data-input capability
Includes accompanying data latches and control circuitry for reliable operation

Applications

Vacuum-fluorescent display driving
Peripheral power driver applications

Procurement Notes

Verify the specific suffix 'EEP' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the 44-pin LPCC package matches the design requirements. Cross-reference the part number with the latest datasheet to confirm availability and any potential obsolescence notices from Allegro MicroSystems before finalizing procurement plans.

Selection Notes

Select this component when a 32-bit serial interface is required for driving high-voltage loads such as VFDs. The integrated PNP active pull-downs and low output-saturation voltages make it suitable for efficient power driving. Consider the 60V minimum output breakdown rating for applications requiring higher voltage tolerance than standard logic drivers.

Part Context

This device belongs to the DABiC-IV family of drivers from Allegro MicroSystems. It serves as an improved replacement for older components like the SN75518N and UCN5818x series. The technology combines CMOS logic efficiency with bipolar output strength, offering a robust solution for display and peripheral driver interfaces.
