TB62705CP

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. FEATURES z Constant-current Output : current with one resistor for 5 to 90mA. z Maximum Clock Frequency : fCLK = 15 (MHz) (Cascade Connecte Operate, Topr = 25°C) z 5V C−MOS Compatible Input z Package : DIP16−P−300−2.54A (TB62705CP) SSOP16−P−225−1.00A (TB62705CF) SSOP16−P−225−0.65B (TB62705CFN) z Constant Output Current Matching: OUTPUT-GND VOLTAGE ≥ 0.4 V ≥ 0.7 V CURRENT MATCHING ±6.0% ±6.0% OUTPUT CURRENT 5~40 mA 5~90 mA TB62705CP TB62705CF TB62705CFN PIN CONNECTION (Top view) GND SERIAL-IN CLOCK LATCH OUTn OUTn OUTn OUTn 1 2 3 4 5 6 7 8 16 VDD 15 R-EXT 14 SERIAL-OUT 13 ENABLE 12 OUTn 11 OUTn 10 OUTn 9 OUTn Weight DIP16-P-300-2.54A: 1.11 g (typ.)
