A6276ELWTR Description

Short technical summary and product information.

The A6276ELWTR 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.

 

Each of the 16 constant-current outputs can deliver up to 75.5mA. The LED drive current is user-determined by a single external resistor. An ENABLE input allows for inter-digit blanking by disabling all output drivers when high. The device also features undervoltage lockout and a low-power CMOS logic.

 

Available in a 24-SOIC surface-mount package, the A6276ELWTR is suitable for applications requiring precise LED current control. The operating temperature range is -40°C to 85°C (TA).
