The Toshiba TB62701N is a monolithic Bi-CMOS integrated circuit specifically designed as a constant current driver for LEDs and LED displays. The device integrates a 16-bit shift register, a latch, AND-gates, and constant current drivers into a single SDIP-24 package.
Key features include the ability to set output currents between 0 and 50mA using an external resistor, compatibility with 5V CMOS inputs, and a maximum clock frequency of 2.5MHz in cascade operation. The datasheet provides detailed electrical characteristics, timing diagrams, pin descriptions, and application circuit examples.
