TYPICAL APPLICATION CIRCUIT
DESCRIPTION
M
anufactured 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.
T
he AIC2803 has a 2.7K Ω 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.
T he AIC2803 features open collector outputs and integral diodes for inductive load transient suppres-sion.
