A6818SEP-T

Overview

The A6818SEP-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 with a supply voltage range of 3V to 5.5V and supports loads up to 60V. It features a maximum output current of 40mA per channel and functions within an operating temperature range of -20°C to 85°C. The component is housed in a 44-PLCC package.

Feature Summary

Combines 32-bit CMOS shift register and latches with bipolar sourcing outputs
Includes PNP active pull-downs for improved drive capability
Features controlled output slew rate to reduce electromagnetic interference
Designed primarily for vacuum-fluorescent display driving applications

Applications

Vacuum-fluorescent display drivers
Peripheral power driver applications
Dot matrix display systems

Procurement Notes

Verify the specific suffix SEP against official datasheets to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as historical records indicate variations between non-compliant and compliant versions. Check for obsolescence notices, as some variants are marked as discontinued. Ensure the ordering part number matches the required lead-free specifications if applicable.

Selection Notes

Select this component when a high-voltage, high-current source driver is needed for serial interface applications. The 60V breakdown voltage and 40mA output rating make it suitable for demanding load conditions. Consider the 44-pin PLCC package constraints for PCB layout. Verify compatibility with 5V logic supplies if interfacing with standard digital controllers.

Part Context

The A6818 belongs to Allegro's DABiC-IV family of display drivers. It serves as an improved replacement for older devices such as the SN75518N and UCN5818x series. The technology combines low-power CMOS logic with robust bipolar output stages to handle higher current loads than previous generations.
