A6275 - 8-Bit Serial Input Constant-Current Latched LED Driver

Description

TheA6275 is specifically designed for LED display applications.

Each BiCMOS device includes an 8-bit CMOS shift register, accompanying data latches, and eight NPN constant-current sink drivers.

The CMOS shift register and latches allow direct interfacing with microprocessor-based systems.

Features

  • Up to 90 mA constant-current outputs.
  • Undervoltage lockout.
  • Low-power CMOS logic and latches.
  • High data-input rate.
  • Pin-compatible with TB62705CP Packages 16-pin DIP (A package) Not to scale 16-pin SOICW (LW package).

A6275 8-Bit Serial Input Constant-Current Latched LED Driver Features and Benefits ▪ Up to 90 mA constant-current outputs ▪ Undervoltage lockout ▪ Low-power CMOS logic and latches ▪ High data-input rate ▪ Pin-compatible with TB62705CP Packages 16-pin DIP (A package) Not to scale 16-pin SOICW (LW package) Description TheA6275 is specifically designed for LED display applications. Each BiCMOS device includes an 8-bit CMOS shift register, accompanying data latches, and eight NPN constant-current sink drivers. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 5 V logic supply, typical serial data-input rates are up to 20 MHz. The LED drive current is determined by the user selection of a single resistor.
