ULN2004AINSG4

Overview

The ULN2004AINSG4 is a high-voltage, high-current NPN Darlington transistor array manufactured by Texas Instruments. It integrates seven independent Darlington pairs within a single package, providing a total of seven input and output channels. Each channel features an internal 10.5kΩ base resistor, enabling direct interface with CMOS logic operating at supply voltages between 6V and 15V. The device includes a common cathode clamp diode connected to the collector supply pin for switching inductive loads. Key electrical ratings include a maximum collector-emitter voltage of 50V and a continuous collector current of 500mA per output.

Feature Summary

Integrates seven NPN Darlington pairs with individual 10.5kΩ base resistors for direct CMOS compatibility
Includes a common cathode clamp diode on the collector supply pin for inductive load protection
Supports high-voltage outputs up to 50V and high-current switching up to 500mA per channel

Applications

Relay driver circuits
Hammer drivers
Lamp drivers
Display drivers (LED and gas discharge)
Line drivers and logic buffers

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead time requirements. Ensure the ordering part number matches the exact package type and temperature rating specified in the datasheet before procurement.

Selection Notes

Select this component when interfacing 6V to 15V CMOS logic directly with high-voltage or high-current loads without external base resistors. Consider the ULN2003A variant if TTL or 5V CMOS compatibility is required instead. Evaluate thermal dissipation capabilities based on the total power consumption of all active channels.

Part Context

This component belongs to the ULx200xA series of Darlington arrays from Texas Instruments. It shares architectural similarities with the ULN2003A but differs in its internal base resistance value to accommodate higher input voltage ranges typical of CMOS families.
