TD62785P/F
TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TD62785P,TD62785F
8CH SOURCE DRIVER
The TD62785P, TD62785F are eight Channel Non−Inverting Source current transistor Array. All units feature input pull−up resistors and output pull−down resistors. These device are specifically designed for multiplexed digit driving of eight digit common−anode LED and also can be employed as a source drivers for multiplexed LED displays using with the TD62381P, TD62381F at standard supply voltage, 5 V. Applications include relay, hammer and lamp drivers.
