Texas Instruments ULN2003LV Low Power 3.3V & 5V Relay Driver

Texas Instruments ULN2003LV Low Power 3.3V and 5V Relay Driver is a low-voltage and low-power upgrade of TI's family of 7-channel Darlington transistor array devices. TI ULN2003LV sink driver features 7 low output impedance drivers to support low voltage relay and inductive coil applications. The low impedance drivers minimize on-chip power dissipation, making it up to 5 times lower for typical 3V relays. ULN2003LV is pin-to-pin compatible with the ULN2003 family of devices in similar packages. ULN2003LV supports 3.3V to 5V CMOS logic input interface, making it compatible to a wide range of microcontrollers and other logic interfaces. ULN2003LV also features an improved input interface that minimizes the input DC current drawn from the external drivers.

Features

7-channel high current sink drivers
Supports up to 8V output pull-up voltage
Supports a wide range of 3V to 5V relay and inductive coils
Low output VOL of 0.4V (Typical) with
- 100mA (Typical) current sink per channel at 3.3V logic input
