16 Bit Constant Current LED Driver with Shift
Register and Latch Functions
TB62706BN
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.

Timing Diagram:
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.
