Overview
The ULN2004AINSG4 is a high-voltage, high-current Darlington transistor array produced by Texas Instruments. This device is part of the ULx2004A series, which features seven NPN Darlington pairs with high-voltage outputs and common-cathode clamp diodes. These diodes are designed for switching inductive loads, making the device suitable for a variety of applications that require robust and reliable switching capabilities.
The ULN2004AINSG4 is specifically designed to operate directly from CMOS devices with supply voltages ranging from 6V to 15V, thanks to its 10.5kΩ series base resistor. This makes it compatible with a wide range of logic families, including TTL, CMOS, PMOS, and DTL.
