DIP Package UDN2981 IC

Recommended for high-side switching applications that benefit from separate logic and load grounds, these devices encompass load supply voltages to 50 V and output currents to -500 mA. These 8-channel source drivers are useful for interfacing between low-level logic and high-current loads. Typical loads include relays, solenoids, lamps, stepper and/or servo motors, print hammers, and LEDs. All devices may be used with 5 V logic systems ? TTL, Schottky TTL, DTL, and 5 V CMOS. The UDN2981A, UDN2982A, and A2982SLW are electrically interchangeable will withstand a maximum output off voltage of 50 V, and operate to a minimum of 5 V. All devices in this series integrate input current limiting resistors and output transient suppression diodes and are activated by active high input. The suffix ?A? (all devices) indicates an 18-lead plastic dual in-line package with a copper lead frame for optimum power dissipation. Under normal operating conditions, these devices will sustain 120 mA continuously for each of the eight outputs at an ambient temperature of +50?C and a supply of 15 V. The suffix ?LW? (UDN2982LW only) indicates an 18-lead surface-mountable wide-body SOIC package; the A2982SLW is provided in a 20-lead wide-body SOIC package with improved thermal characteristics. The UDN2982A, UDN2982LW, and A2982SLW drivers are also available for operation over an extended temperature range to -40?C. To order, change the prefix ?UDN? to ?UDQ? or the suffix ?SLW? to ?ELW?. These packages are available in Pb (lead) free variants (suffix ?-T?), with 100% matte-tin lead frame plating.
