TD62824P

TD62824P TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC TD62824P 8 × 3 PARALLEL SHIFT REGISTER / DRIVER The TD62824P is a general purpose 24 bit driver IC consisting of 8 block 3 bit shift register and 24 bit driver (open collector). The TD62824P is best suited as a 24 dot printer head driver. FEATURES l Power−down function for reducing power consumption during standby or when printing is not made. (ICC off < 10 µA) l Independent 2 output enable terminals (even / add outputs) l Effective as measures for regenerative effect during high−speed and high−density printing. l 8bit parallel input and 3bit parallel shift configuration : High−speed operation and direct interface with CPU. l Large output drive capacity l Output with standing voltage ········ 30 V Output current ································ 80 mA DC 150 mA 10% l Built−in CR−Timer for load burning prevention. l Less output saturation voltage difference in package : Within ±50mV (standard) at IOUT = 120 mA Weight: 6.37 g (Typ.)
