TB62705CP/CF/CFN
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 compensating 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)
