7003 HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAY
●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.
●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.
●The high sustaining voltage rating of this power array makes it ideal for inductive load applications where Zener diode flyback techniques are used. The increased flyback voltage provides a much faster inductive load turn-off current decay that is especially useful with dc stepper motors, solenoids, and print heads.
●Both devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. The ULN7003A is supplied in a 16-pin plastic dual in-line package with a copper lead frame to maximize device power dissipation capabilities. The ULN7003LW is furnished in a 16-lead small-outline wide-body package for surface-mount applications.
