Note that the ULN2000A Series (dual in-line package) and ULN2000L series (small-outline IC package) are electrically identical and share a common pin number assignment.

Recommended for high-side switching applications that benefit from separate logic and load grounds, these devices encompass load supply voltages to 80 V and output currents to -500mA. The UDN2981A through UDN2984A/LW 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 and UDN2982A/LW are interchangeable, will withstand a maximum output OFF voltage of 50 V and operateto a minimum of 5 V;the UDN2983A and UDN2984A/LW drivers are interchangeable, will whthstand an output voltage of 80 V, and operate to a minimum of 35 V. All devices in this series integrate input current limiting resistors and output transient suppression diodes, and are activated by an active high input.

The suffix’A’(all devices) indicates an 18-lead plasitic dual in-line package with copper lead frame for optimum power dissipation. Under normal operating conditions, these devices will sustain 120 mA continu- ously for each of the eight outputs at an ambient temperature of +50 and a supply of 15 V

The suffix ‘LW’ (UND2982LW and UDN2984LW only) indicates

a surface-mountable wide-body SOIC pakage. All devices are also available for operation between-40 and +85 To order, change the prefix form ‘UDN’ to ‘UDQ’.
