TD62308APG,TD62308AFG
4ch Low Input Active High-Current Darlington Sink Driver
The TD62308APG/AFG is a non−inverting transistor array
which is comprised of four NPN darlington output stages and
PNP input stages.
This device is low−level input active driver and is suitable for
operation with 5-V TTL, 5-V CMOS and 5-V Microprocessor
which have sink current output drivers.
Application include relay, hammer, lamp and stepping motor
drivers.

Precautions for Using
(1)
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
, COMMON and GND line since IC may be
destroyed due to short−circuit between outputs, air contamination fault, or fault by improper grounding.
If a TD62308APG/AFG is being used to drive an inductive load (such as a motor, solenoid or relay), Toshiba
recommends that the diodes (pins 9 and 16) be connected to the secondary power supply pin so as to absorb
the counter electromotive force generated by the load. Please adhere to the device’s absolute maximum ratings.
Toshiba recommends that zener diodes be connected between the diodes (pins 9 and 16) and the secondary
power supply pin (as the anode) so as to enable rapid absorption of the counter electromotive force. Again,
please adhere to the device’s absolute maximum ratings.
