TI ULN2004AN

继电器，螺线管驱动器7不需要500mA

Overview

All trademarks are the property of their respective owners.

The ULx2004A devices have a 10.5-k? series base resistor to allow operation directly fromCMOS devices that use supply voltages of 6 V to 15 V. The required input current of the ULx2004Adevice is below that of the ULx2003A devices, and the required voltage is less than that requiredby the ULN2002A device.

Features
