XD2804 – Darlington Transistor Array – Xinluda

The Xinluda XD2804 is a high-voltage, high-current octal Darlington transistor array (ULN2804-type) with eight NPN Darlington pairs, integral free-wheeling clamp diodes, and 6 V to 15 V CMOS/PMOS-compatible inputs in a DIP-18 package.

The Xinluda XD2804 is a high-voltage, high-current driver IC comprised of eight NPN Darlington pairs in a single 18-pin dual in-line (DIP-18) package. Functionally equivalent to the industry-standard ULN2804, it integrates free-wheeling clamp diodes on every output, making it ideal for switching inductive loads such as relays, solenoids, stepper motors, and lamps. The XD2804 input stage is specified for 6 V to 15 V CMOS/PMOS-type logic, allowing it to be driven directly from many microcontroller and logic outputs.

Key Features

• Eight independent NPN Darlington driver channels in one package
• Output sustaining voltage: 50 V minimum (V_CE)
• Continuous output current: up to 500 mA per output
• Output saturation voltage V_CE(sat): approximately 1.3 V
• Integral free-wheeling clamp diodes for inductive-load transient suppression
• Input voltage range: 6 V to 15 V (CMOS/PMOS-type logic)
• Maximum input voltage: 30 V
• Open-collector outputs for flexible load connection
• Operating temperature range: -40 C to +85 C
• Package: DIP-18 (through-hole)

Applications

• Relay and solenoid drivers
• Stepper and DC motor drivers
• Incandescent and LED lamp / display drivers
• Print hammer and gate drivers
• General-purpose high-current logic-to-load interfacing

Why Source XD2804 from Pacific Component Xchange
