DIP Package UDN2981 IC

DIP Package UDN2981 IC

These devices are 8-channel source drivers that can switch high-side loads up to 50 V and -500 mA. They are suitable for interfacing low-level logic circuits with high-current loads, such as relays, solenoids, lamps, stepper or servo motors, print hammers, and LEDs.
They are compatible with 5 V logic systems, such as TTL, Schottky TTL, DTL, and 5 V CMOS. The UDN2981A, UDN2982A, and A2982SLW have the same electrical characteristics and can withstand a maximum output voltage of 50 V when off. They can operate with a minimum supply of 5 V. They have input current limiting resistors and output transient suppression diodes. They are activated by active high input signals.
The suffix ‘A’ indicates an 18-lead plastic DIP package with a copper lead frame for better heat dissipation. These devices can handle 120 mA continuously for each output at an ambient temperature of +50°C and a supply of 15 V. The suffix ‘LW’ indicates an 18-lead wide-body SOIC package for surface mounting. The A2982SLW has a 20-lead wide-body SOIC package with enhanced thermal performance. The UDN2982A, UDN2982LW, and A2982SLW are also available for extended temperature range operation down to -40°C. To order, replace the prefix ‘UDN’ with ‘UDQ’ or the suffix ‘SLW’ with ‘ELW’. These packages have Pb-free variants (suffix ‘-T’) with 100% matte-tin plating on the lead frame.
This product is also known as 2981, UDN2981A, UDN2981, UDN2981 LED Driver, UDN2981A LED Driver, UDN2981A RELAY Driver, 2981 ELD Driver, UDN2981A Display Driver, UDN2981 Multi Function Driver, or UDN2981A Multifunction Driver.
