Overview
2981 THRU 2984 UDN2981A thru UDN2984A 1 2 3 4 5 6 7 8 VS 18 17 16 15 14 13 12 11 GND 8-CHANNEL SOURCE DRIVERS 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 interchangeable, 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 o...
