AIC2003
7-CHANNEL DARLINGTON DRIVERS
SPEC NO: DS-2003-00
FEATURES
Improved Replacement for ULN2803.
Fast Turn-on and Turn-off.
TTL/CMOS Compatible.
■
DESCRIPTION
Manufactured with the standard bipolar process,
the AIC2003 is a high-voltage, high-current 7-
channel Darlington array, with each of the output
transistors capable of sinking peak load current of
700mA and capable of withstanding at least 35V in
the OFF state.
The AIC2003 has a 2.7KΩ series base resistor to
each Darlington pair and thus allows operation
directly with TTL or CMOS logic circuitry operating
at a supply voltage of 5V. Outputs of the drivers
can be paralleled for higher load current capability.
These make the AIC2003 ideally suited for
numerous interfaces between low-level logic
circuitry and high-power peripheral loads,
particularly those beyond the capabilities of
standard logic buffers. Typical loads include
relays, solenoids, stepping motors, heaters,
multiplexed LED, and incandescent displays.
The AIC2003 features open collector outputs and
integral diodes for inductive load transient
suppression.
APPLICATIONS
Stepping Motor Driver.
Relay Driver.
LED Driver.
Solenoid Driver.
