TB62706BF

TB62706BN/BF TOSHIBA Bi−CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC TB62706BN,TB62706BF 16BIT SHIFT REGISTER, LATCHES & CONSTANT CURRENT DRIVERS The TB62706BN, TB62706BF is specifically designed for LED and LED DISPLAY constant current drivers. This constant current output circuits is able to set up external resistor (IOUT = 5~90 mA). (Note) This IC is monolithic integrated circuit designed to be used together with Bi−CMOS process. The devices consist of 16bit shift register, latch, AND−GATE and Constant Current Drivers. FEATURES Constant Current Output : Can set up all output current with one resister for 5 to 90 mA. Maximum Clock Frequency : fCLK = 15 (MHz) (Cascade Connected Operate, Topr = 25°C) 5 V C−MOS Compatible Input Package : SDIP24−P−300−1.78~1.778mmPitch~ (TB62706BN) SSOP24−P−300−1.00B~1.0mmPitch~ (TB62706BF) Constant Output Current Matchong: OUTPUT−GND VOLTAGE ≥ 0.4 V ≥ 0.7 V CURRENT MATCHING ±6.0% ±6.0% OUTPUT CURRENT 5~40 mA 5~90 mA Note: TB62706BF can be used under limited PD (PD ≤ 1.04 W, with PCB) (Note) TB62706BN TB62706BF Weight SDIP24-P-300-1.78 : 1.22 g (typ.) SSOP24-P-300-1.00B : 0.32 g (typ.) 1 2003-05-14 PIN CONNECTION (Top view) BLOCK DIAGRAM TIMING DIAGRAM TB62706BN/BF Note: Latches are level sensitive, not rising edges sensitive and not syncronus CLOCK. Input of LATCH−terminal to H Level, data passes latches, and input to L level, data hold latches. Input of ENABLE−terminal to H level, all output (OUT0~15) do off. 2 2003-05-14 T...
