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
