FEATURES
Improved Replacement for ULN2803.
Fast Turn-on and Turn-off.
TTL/CMOS Compatible.
DESCRIPTION
ꢀ
Manufactured with the standard bipolar process, the
AIC2803 is a high-voltage, high-current 8-channel
Darlington array, with each of the output transistors
capable of sinking peak load current of 500mA and
capable of withstanding at least 50V in the OFF state.

APPLICATIONS
Stepping Motor Driver.
Relay Driver.

ꢀ
ꢀ
ꢀ
The AIC2803 has a 2.7KΩ series base resistor to
each Darlington pair and thus allows operation di-
rectly 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 AIC2803 ideally suited for numerous in-
terface 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.
