The TD62781AFG(5,EL) is a high-voltage, high-current sink driver array from Toshiba Semiconductor and Storage. The (5,EL) suffix likely refers to specific packaging or quality control characteristics. It is designed to interface between logic-level control signals and higher power loads, providing a convenient way to drive multiple loads from a microcontroller or other logic device.

Applications

• Driving relays (sinking configuration)
• Driving solenoids (sinking configuration)
• Driving stepper motors (sinking configuration)
• Driving LED displays (common anode configuration)
• Driving small DC motors (sinking configuration)

Features

• High output voltage: 50V (minimum)
• High output current: 350mA (maximum) per channel
• 8 independent channels
• TTL and 5V CMOS logic compatible inputs
• Integrated clamp diodes for inductive load protection
• Package: SOP-18 (likely a small outline package)

Benefits

• Provides a simple interface between low-power control logic and high-power loads.
• Protects the driver from voltage transients caused by inductive loads, ensuring reliable operation.
• Reduces the number of discrete components, simplifying board layout and reducing cost.
• Offers versatile control capabilities with its multiple independent channels.
• Compatible with standard TTL and CMOS logic levels.

Additional Details

The TD62781AFG(5,EL) features integrated clamp diodes to protect the outputs from voltage spikes generated when switching inductive loads. The inputs are designed to be compatible with standard TTL and 5V CMOS logic levels. The SOP-18 package allows for surface mounting, saving board space compared to traditional DIP packages. The (5,EL) suffix likely refers to specific testing or handling characteristics. Always consult the datasheet for comprehensive details, including electrical characteristics, thermal considerations, and package dimensions. Operating temperature range typically extends from -40°C to +85°C. As a sink driver, it connects the load to ground when activated.
