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 5Vlogic 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 package is a 20-pin wide-body SOIC with improved
thermal characteristics compared to the 18-pin SOIC version
it replaces (100% pin-compatible electrically).
The package is lead (Pb) free, with 100% matte-tin leadframe
plating.
