8-BIT SHIFT REGISTER, LATCHES & CONSTANT-CURRENT DRIVERS
The TB62705CP / CF / CFN are specifically designed for LED and
LED DISPLAY constant-current drivers.
These constant-current output circuits can support the set-up of
an external resistor (IOUT = 5~90mA).
This IC is a monolithic integrated circuit designed to be used
together with Bi-CMOS process.
The devices consist of an 8-bit shift register, latch, AND-GATE
and constant-current drivers.
