Overview

A6277 8-Bit Serial Input Constant-Current Latched LED Driver Features and Benefits ▪ Up to 150 mA constant-current outputs ▪ Undervoltage lockout ▪ Low-power CMOS logic and latches ▪ High data input rate ▪ Similar to Toshiba® TD62715FN ▪ High/low output current function ▪ Digital dimming control Package: 20-pin SOICW (suffix LW) Description The A6277 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 ...
