ULS-2801H/R THROUGH Co > SPRAGUE ULS-2825H/R THE MARK OF RELIABILITY Integrated Circuits SERIES ULS-2800H AND ULS-2800R HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS MIL-STD-883 Compliant FEATURES @ TTL, DTL, PMOS, or CMOS Compatible Inputs @ Peak Output Current to 600 mA Transient-Protected Outputs Side-Brazed Hermetic Package @ Cer-DIP Hermetic Package @ High-Reiiability Screening to MIL-STD-883, Class B @ 55C to + 125C Temperature Range ESIGNED TO SERVE as interface between low-level logic circuitry and high-power loads, Series ULS-2800H and ULS-2800R arrays consist of eight silicon NPN Darlington power drivers on a common monolithic substrate. They are ideally suited to driving relays, solenoids, lamps, and other devices in high-reliability military or aerospace ap- plications with up to 3 A output current per package. These devices are screened to MIL-STD-883, ber Designation Class B and are supplied in either the popular glass/ 50V 95V metal side-brazed 18-pin hermetic package (s 500 mA 600 mA 500 mA H) or ceramic/glass cer-DIP hermetic pa Part Number (suffix R). Both package styles conform z mensional requirements of MIL-M- rated for operation over the full milit range of 55C to +125C.
