A6276EA Description

Short technical summary and product information.

The Allegro MicroSystems A6276EA is a BiCMOS device designed for LED-display applications, featuring a 16-bit CMOS shift register, data latches, and 16 NPN constant-current sink drivers. It allows direct interfacing with microprocessor-based systems with a typical serial data input rate of up to 20 MHz when using a 5V logic supply.

 

The device provides up to 90 mA constant-current outputs, with the specific current determined by a user-selected resistor. It includes undervoltage lockout and a low-power CMOS logic. A CMOS serial data output enables cascaded connections for applications requiring additional drive lines. All output drivers can be disabled with an ENABLE input high for inter-digit blanking.

 

The A6276EA is available in a 24-pin DIP (Dual In-line Package) through-hole package, measuring 0.300 inches (7.62mm) wide. It operates within an ambient temperature range of -40°C to 85°C. This LED driver is a functional replacement for the TB62706BN/BF.

 

All packages are lead (Pb) free, with 100% matte tin leadframe plating.
