2981 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'.
