TB62705CP/CF/CFN
TOSHIBA Bi−CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC
TB62705CP,TB62705CF,TB62705CFN
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.
