TD62308APG/AFG TOSHIBA Bipolar Digital Integrated Circuit Silicon Monolithic TD62308APG,TD62308AFG 4ch Low Input Active High-Current Darlington Sink Driver The TD62308APG/AFG is a non inverting transistor array TD62308APG 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. TD62308AFG Features Output current (single output): 1.5 A (max) High sustaining voltage output: 50 V (min) Output clamp diodes Input compatible with TTL and 5 V CMOS Low level active inputs Standard supply voltage Two V terminals V , V (separated) CC CC1 CC2 Weight GND and SUB terminal = Heat sink DIP16-P-300-2.54A: 1.11 g (typ.)

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 , COMMON and GND line since IC may be CC destroyed due to shortcircuit between outputs, air contamination fault, or fault by improper grounding. (2) 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 devices 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 devices absolute maximum ratings.
