ULN2003

Short Description:

ULN2003 is a single-chip integrated high voltage, high current Darlington tube array, The circuit contains seven independent Darlington tube drive single channel. The circuit is designed with continuous diode, which can be used to drive relay,stepping motor and other inductive loads. A single darlington collector can output 500mA current. Higher output current capacity can be achieved by connecting darlington tubes in parallel.

Exceeding the absolute maximum rating may cause permanent damage to the chip. These are only maximum ratings and prolonged use at absolute maximum ratings may affect the reliability of the chip.
All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
Maximum power dissipation is a function of TJ(max), θJC, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJC. Operating at the absolute maximum TJ of 150°C can affect reliability.
