8 Channel Source Driver
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.
