TB62706BN/BF
16 Bit Constant Current LED Driver with Shift
Register and Latch Functions
Product Description:
The TB62706BN/BF is specifically designed for
LED display applications. The Bi-CMOS device has
16 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 16 outputs effectively compensating for
the inherent circuit and component variables which
affect the brightness of the LEDs.
Features:
• 16 Constant Current Output Channels
• Current Programmable from 5-90mA
• 5V CMOS Compatible Inputs
• 15MHz Max Clock Frequency (Cascade)

Terminal Description & Pin Out:
PIN No. PIN NAME FUNCTION
1 GND GND termi nal for control logic.
2 SERIAL-IN Input terminal of a serial-data for shift-register
3 CLOCK Iinput terminal of a clock for data shift to up-edge.
4LATCH
Input terminal of a data strobe. Latches passes data with "H" level input of
LATCH-terminal, and hold data with "L" level input.
5~20 OUT0~15 Output terminals
21 ENABLE Input terminal of output enable. All outputs (OUT~15) do off with "H" level input
of ENABLE-terminal, and do on with "L" level input.
22 SERIAL-OUT Output terminal of a serial-data for next SERIAL-IN terminal.
23 R-EXT Input terminal of connects with a resister for to set up all output current.
24 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.
