2 / 11 page HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAYS FEATURES s TTL, DTL, PMOS, or CMOS Compatible Inputs s Output Current to 500 mA s Output Voltage to 95 V s Transient-Protected Outputs s Dual In-Line Package or Wide-Body Small-Outline Package 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 interfac- ing 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 ham- mers, multiplexed LED and incandescent displays, and heaters. All devices feature open-collector outputs with integral clamp diodes. The ULx2803A, ULx2803LW, ULx2823A, and ULN2823LW have series input resistors selected for operation directly with 5 V TTL or CMOS. These devices will handle numerous interface needs — particularly those beyond the capabilities of standard logic buffers. The ULx2804A, ULx2804LW, ULx2824A, and ULN2824LW have series input resistors for operation directly from 6 V to 15 V CMOS or PMOS logic outputs. The ULx2803A/LW and ULx2804A/LW are the standard Darlington arrays. The outputs are capable of sinking 500 mA and will withstand at least 50 V in the off state. Outputs may be paralleled for higher load current capability. The ULx2823A/LW and ULx2824A/ LW will withstand 95 V in the off state. These Darlington arrays are furnished in 18-pin dual in-line plastic packages (suffix ‘A’) or 18-lead small-outline plastic packages (suffix ‘LW’). All devices are pinned with outputs opposite inputs to facilitate ease of circuit board layout. Prefix ‘ULN’ devices are rated for operation over the temperature range of -20 °C to +85°C; prefix ‘ULQ’ devices are rated for operation to -40 °C. x = Character to identify specific device. Characteristic shown applies to family of devices with remaining digits as shown. See matrix on next page. 2803 THRU 2824 18 17 15 14 13 712 811 910 1 2 4 5 6 Dwg.
