TD62C853F

TD62C853,854F TOSHIBA Bi−CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC TD62C853F,TD62C854F 8BIT SERIAL−IN PARALLEL−OUT SHIFT REGISTER / LATCH DRIVERS The TD62C853F and TD62C854F are monolithic circuits designed to be used together with Bi−CMOS integrated circuits. The devices consist of a 8 bit shift register, 8 bit latches, and 8 output circuits. FEATURES l 8 bit serial−in parallel−out shift register / latch driver (Bi−CMOS process) l Maximum output sustaining voltage ; 50 V l Maximum output current ; TD62C853F 200 mA / ch (Low saturation type) TD62C854F 500 mA / ch (darlington type) l CMOS compatible inputs l Package ; SSOP24−P−300−1.00 Weight: 0.32 g (Typ.) Note: S−OUT pin is sensitive against Latch−up. (Latch−up performance is under 30 mA) Please connect an external resistor to S−OUT pin in series due to protect this device from Latch−up.
