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.
FEATURES
· Constant-current output:
A single resistor can be used to set any output current in the
range −5~−90 mA.
· Maximum clock frequency: fCLK = 15 MHz
(operating while connected in cascade, Topr = 25°C)
· 5-V CMOS compatible input
· Packages:
P-type: DIP20-P-300-2.54A
F-type: SSOP24-P-300-1.00
FN-type: SSOP20-P-225-0.65A
