Description

Recommended for high-side switching applications that benefit

from separate logic and load grounds, these devices encompass

load supply voltages to 50 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 device packages offered are

electrically interchangeable, and will withstand a maximum

output off voltage of 50 V, and operate to a minimum of 5 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” 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” package is provided in a 20-pin wide-body

SOIC package with improved thermal characteristics compared

to the 18-pin SOIC version it replaces (100% pin-compatible

electrically). The A2982ELW driver is available for operation

over an extended temperature range, down to -40°C.

These packages are lead (Pb) free, with 100% matte-tin

leadframe plating.
