2984 General Description
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 -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, UDN2982LW, and A2982SLW are electrically interchangeable, will withstand a maximum output off voltage of 50 V, and operate to a minimum of 5 V; the UDN2983A,UDN2984A, UDN2984LW, and A2984SLW drivers are electrically inter-changeable, will withstand 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 plastic dual in-line package with 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 and UDN2984LW only) indicates an 18-lead surface-mountable wide-body SOIC package; the A2982SLW and A2984SLW are provided in a 20-lead wide-body SOIC package with im- proved thermal characteristics.
The UDN2982A, UDN2982LW, A2982SLW, UDN2984A, UDN2984LW, and A2984SLW 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'.

2985 General Description
Recommended for applications requiring separate logic and load grounds,load supply voltages to 30 V, and load currents to 250 mA, the UDN2985A source driver is used as an interface between standard low-power digital logic and LEDs, relays, and solenoids. The outputs feature saturated transistors for low collector-emitter saturation voltages.
The UDN2985A driver is for use with 5 V logic systems: TTL, Schottky TTL, DTL, and CMOS. This device has a minimum output breakdown rating of 30 V with a minimum output sustaining voltage of 15 V. The output is switched on by an active-high input level.
Under normal operating conditions, this device can source up to 120 mA for each of the eight outputs at an ambient temperature of 75°C and a supply voltage of 15 V. It incorporates input current-limiting resistors and output transient-suppression diodes.
The UDN2985A source driver is supplied in an 18-pin dual in-line package. All inputs are on one side of the package, output pins on the other, to simplify printed wiring board layout.
