8 Bit Constant Current LED Driver with

Shift Register and Latch Functions Product Description: The TB62705CP/CF/CFN is specifically designed for LED display applications. The Bi-CMOS device has 8 Bi-Polar constant current output channels and includes CMOS shift register and latch functions. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-90mA and is held constant across all 8 outputs effectively compen- sating for the inherent circuit and component variables which affect the brightness of the LEDs. Features:

  • 8 Constant Current Output Channels
  • Current Programmable from 5-90mA
  • 5V CMOS Compatible Inputs
  • 15MHz Max Clock Frequency (Cascade) Block Diagram: SSOP16-P-225-1.00A TB62705CF Weight: 0.14g(typ) SSOP16-P-225-0.65B TB62705CFN Weight: 0.07g(typ) NEW! Ultra Small Surface Mount Package DIP16-P-300-2.54A TB62705CP Weight: 1.11g(typ) Company Headquarters

LATCH Inout terminal of a data strobe. (Latches pass data with "H" level inputof LATCH-terminal, and hold data with "L" level input.) 5~12 OUT0~7 Output terminals ENABLE Input Teminal of output enable. (All outputs (OUT0~7) do off with "H" level input of ENABLE terminal, and on with "L"level input.) SERIAL-OUT Output terminal of serial data for next SERIAL-IN terminal. R-EXT Constant Current Programming through external resistor VDD 5V Supply voltage terminal Latches are: 1. Level Sesitive 2. Not edge sensitive 3. Not clock synchronous 4. Passing Data when LATCH is H 5. Hold Data when LATCH is L All Outputs are OFF when ENABLE is H and ON when ENABLE is L.
