A6276EA-T

Overview

The A6276EA-T is a linear LED driver IC featuring a 16-bit serial input shift register and data latches. It provides 16 constant-current sink outputs with a typical drive current of 75.5mA per channel. The device operates on a supply voltage range of 4.5V to 5.5V, with an output voltage capability of 4V. It supports high-speed serial data input rates up to 20MHz and includes under-voltage lockout protection. The component is housed in a 24-DIP package with a through-hole mounting type.

Feature Summary

Integrates a 16-bit CMOS shift register and data latches for direct microprocessor interfacing
Provides 16 independent constant-current sink drivers for LED display applications
Supports cascade connections via a dedicated CMOS serial data output pin

Applications

LED display systems requiring serial control
High-density LED matrix driving
Microprocessor-based lighting control interfaces

Procurement Notes

Verify the specific suffix EA-T against the manufacturer's latest datasheet to confirm package dimensions and thermal characteristics. Confirm availability status as distribution listings may indicate end-of-life or obsolete status for this specific variant. Ensure the design accommodates the 24-DIP through-hole form factor and 5V logic supply requirements.

Selection Notes

Select this component when a multi-channel constant-current solution with serial interface control is required. It serves as a functional replacement for legacy parts like the TB62706BN/BF. Consider the 24-DIP package constraints and 5V logic level compatibility during system architecture planning.

Part Context

This part belongs to Allegro's A6276 family of 16-bit serial-input constant-current latched LED drivers. The family includes variants such as the A6275 series (8-bit) and different package options like SOIC or DIP. These devices are designed specifically for LED-display applications where serial data processing and uniform current sinking are critical.

Replacement Considerations

The A6276EA-T is documented as a functional replacement for the Toshiba TB62706BN/BF. Verify pin-to-pin compatibility and electrical specifications before substitution.
