| AIC2803 8-CHANNEL DARLINGTON DRIVERS SPEC NO: DS-2803-00 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. The AIC2803 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 AIC2803 ideally suited for numerous interface between low-level logic circuitry and highpower 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 AIC2803 features open collector outputs and integral diodes for inductive load transient suppression. APPLICATIONS Stepping Motor Driver. Relay Driver. LED Driver. Solenoid Driver.
