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 2.7K ? 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.
