TD62381PG/FG
TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT
SILICON MONOLITHIC
TD62381PG,TD62381FG
8CH LOW SATURATION SINK DRIVER
The TD62381PG and TD62381FG are comprised of eight NPN
low saturation drivers. These devices are specifically designed for
multiplexed digit driving of eight digit common−cathode LED and
also can be employed as a sink driver for multiplexed LED
displays using with the TD62785P and TD62785F at standard
supply voltage, 5 V.
Applications include relay, hammer, lamp and LED display
drivers.

PRECAUTIONS for USING
This IC does not include built-in protection circuits for excess current or overvoltage.
If this IC is subjected to excess current or overvoltage, it may be destroyed.
Hence, the utmost care must be taken when systems which incorporate this IC are designed.
Utmost care is necessary in the design of the output line, V
CC
, and GND line since IC may be destroyed due to
short−circuit between outputs, air contamination fault, or fault by improper grounding.
