Technical Specifications

The TD62307P contains seven Darlington transistor pairs. Each transistor pair includes an input resistor and a flyback diode to protect against voltage spikes when driving inductive loads. The device operates over a wide temperature range. The input voltage is typically compatible with TTL and 5V CMOS logic levels, simplifying integration with a variety of control systems. The maximum output voltage is rated at 50V, and the maximum output current is 500mA per channel. The device is housed in a 16-pin DIP package, making it easy to mount on printed circuit boards. Internal clamp diodes are included for each output to protect the device from back EMF generated when switching inductive loads.
