Each of the seven outputs sinks up to 500 mA continuously with a maximum load voltage of 50 V, and the inputs are inverting with a 1:1 ratio — a logic high on the input turns the output on, pulling the load to ground. The integrated Darlington pairs give you a current gain of about 1000, so a few milliamps from a microcontroller or PLC output can switch a 500 mA relay coil without an external driver transistor. ## Package and board-fit for a field-swap The 1.0 mm pitch on the TSSOP-16 body means you can route it on a two-layer board without micro-vias; just keep the GND pin (pin 9) trace wide enough for the return current from all seven channels. Operating from -40°C to 70°C, it covers most indoor industrial and commercial environments — fine for a control cabinet or a test fixture, but not rated for under-hood automotive without a temperature-grade check. ## Active production and compliance posture The part is ROHS3 compliant, so it meets the latest EU restriction on hazardous substances — no exemption declarations needed for most commercial builds.","metaTitle":"TI ULN2003APWR Darlington Transistor Array, 7-Ch, 50V, 500mA","metaDescription":"Texas Instruments ULN2003APWR, 7 NPN Darlington array, 50V load, 500mA per channel, low-side driver.
