The A6276EA from Allegro MicroSystems is a BiCMOS device designed for LED-display applications. It integrates a 16-bit CMOS shift register, data latches, and 16 NPN constant-current sink drivers. This configuration allows for direct interfacing with microprocessor-based systems, supporting serial data input rates up to 20 MHz with a 5V logic supply.
The device offers constant-current outputs capable of up to 90 mA, determined by a user-selected resistor. An ENABLE input allows for inter-digit blanking by disabling all output drivers when high. The A6276EA is available in three package styles: DIP, SOIC, and TSSOP. The DIP package, in particular, is suitable for continuous operation at maximum rated current over the operating temperature range of -40°C to 85°C.
Key features include undervoltage lockout, low-power CMOS logic, and the ability to cascade connections via a CMOS serial data output. It serves as a functional replacement for the TB62706BN/BF.
This specific variant, A6276EA, is supplied in a 24-pin DIP package and is suitable for through-hole mounting. It operates within an ambient temperature range of -40°C to 85°C.
