ULN2803A OCTAL PERIPHERAL DRIVER ARRAYS

Octal High Voltage, High Current Darlington Transistor Arrays

The eight NPN Darlington connected transistors in this family of arrays are ideally suited for interfacing between low logic level digital circuitry (such as TTL, CMOS or PMOS/NMOS) and the higher current/voltage requirements of lamps, relays, printer hammers or other similar loads for a broad range of computer, industrial, and consumer applications. All devices feature open–collector outputs and free wheeling clamp diodes for transient suppression.
The ULN2803 is designed to be compatible with standard TTL families while the ULN2804 is optimized for 6 to 15 volt high level CMOS or PMOS.

ULN2803A High Voltage High Current Darlington Arrays

HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS

Featuring continuous load current ratings to 500 mA for each of the drivers, the Series ULN28xxA/LW and ULQ28xxA/LW high voltage, high-current Darlington arrays are ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads. Typical power loads totaling over 260 W (350 mA x 8, 95 V) can be controlled at an appropriate duty cycle depending on ambient temperature and number of drivers turned on simultaneously. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes.

FEATURES
■ TTL, DTL, PMOS, or CMOS Compatible Inputs
■ Output Current to 500 mA
■ Output Voltage to 95 V
■ Transient-Protected Outputs
■ Dual In-Line Package or Wide-Body Small-Outline Package

ULN2803A EIGHT DARLINGTON ARRAYS

DESCRIPTION
The ULN2801A-ULN2805Aeach contain eight darlington transistors with common emitters and inte
gral suppression diodes for inductive loads. Each darlington features a peak load current rating of
600mA (500mA continuous) and can withstand at least 50V in the offstate.Outputs may be paralleled for higher current capability.Five versions are available to simplify interfacing to standard logic families : the ULN2801A is designed for general purpose applications with a current limit
resistor ; the ULN2802Ahas a 10.5kΩ input resistor and zener for 14-25V PMOS; the ULN2803Ahas a 2.7kΩinput resistor for 5V TTL and CMOS ; the ULN2804A has a 10.5kΩinput resistor for 6-15V
CMOS and the ULN2805A is designed to sink a minimum of 350mA for standard and Schottky TTL
where higher output current is required. All types are supplied in a 18-lead plastic DIP with
a copper lead fromand featurethe convenient input
