Data Sheet 29304.10A 7003 HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAY 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 Integrating seven high-voltage, high-current npn Darlingtons into a monolithic power array, the ULN7003A AND ULN7003LW are designed for interfacing between TTL or CMOS logic and a variety of peripheral loads. The seven open-collector Darlington outputs are specified for 135 V minimum breakdown and 90 V minimum sustaining. Included are integral power diodes for switching inductive loads. Typical applications include relays, lamps, print heads and hammers, solenoids, and level shifting to power discretes. T C The ULN7003A/LW include input current-limiting resistors compatible with the drive capabilities of TTL and (most) CMOS operating at a nominal logic supply of 5 V. Operation with 12 V CMOS may require additional input current limiting. U D Dwg. No. A-9594 Note the ULN7003A (DIP) and the ULN7003LW (SOIC) are electrically identical and share a common terminal number assignment.
