TB62710P/F/FN
TOAHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
TB62710P, TB62710F, TB62710FN
8-Bit Constant-Current LED Driver for Cathode Common LED
The TB62710P, TB62710F and TB62710FN are specifically
designed for use as LED and LED display (cathode-common)
Constant-current drivers.
The constant-current output circuits can be set up using an
external resistor (IOUT
= −90
mA max).
These ICs are monolithic integrated circuits have been
designed using the Bi-CMOS process.
The devices consist of an 8-bit shift register, a latch, an
ANDgate and constant-current drivers.
