2981 2982 8-Channel Source Drivers
TTL, DTL, PMOS, CMOS compatible inputs output source current capability Transient-protected outputs Output breakdown voltage SOIC packaging
Recommended high-side switching applications that benefit from separate logic load grounds, these devices encompass load supply voltages output currents -500 These 8-channel source drivers useful interfacing between low-level logic high-current loads. Typical loads include relays, solenoids, lamps, stepper and/or servo motors, print hammers, LEDs. devices used with logic systems TTL, Schottky TTL, DTL, CMOS. device packages offered electrically interchangeable, will withstand maximum output voltage operate minimum devices this series integrate input current limiting resistors output transient suppression diodes, activated active high input. suffix indicates 18-lead plastic dual in-line package with copper lead frame optimum power dissipation. Under normal operating conditions, these devices will sustain continuously each eight outputs ambient temperature +50°C supply suffix "LW" package provided 20-pin wide-body SOIC package with improved thermal characteristics compared 18-pin SOIC version replaces (100% pin-compatible electrically). A2982ELW driver available operation over extended temperature range, down -40°C. These packages lead (Pb) free, with 100% matte-tin leadframe plating.
