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.)

PRECAUTIONS for USING
This IC does not integrate protection circuits such as overcurrent and overvoltage protectors.
Thus, if excess current or voltage is applied to the IC, the IC may be damaged. Please design the IC so that
excess current or voltage will not be applied to the IC.
Utmost care is necessary in the design of the output line, VCC and GND line since IC may be destroyed due to
short−circuit between outputs, air contamination fault, or fault by improper grounding.
