Relay Driver supports low voltage relays from 1.8-5 V.August 24, 2012 -
Available in 10 x 4 mm, 16-pin SOIC and 5.1 x 4.5 mm, 16-pin TSSOP packages, 7-channel Model ULN2003LV replaces multiple discrete components with single device to drive data relays and rails within telecommunications equipment. Input resistor capacitor snubber optimizes driver performance in noisy operating conditions, while internal input pull-down resistor allows input logic to be tri-stated. CMOS logic input interface is compatible with wide range of microcontrollers and other logic interfaces.

TI Introduces the First Fully Integrated 1.8-V and 3.3-V, Seven-Channel Relay Driver
Interface device reduces board space by 80 percent for telecommunications applications
DALLAS, -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced the industry's first fully-integrated, seven-channel relay driver that can support low-voltage relays from as low as 1.8 V up to 5 V. The ULN2003LV relay driver replaces a handful of discrete components with a single device to drive lower voltages for data relays and rails within telecommunications equipment. Using the ULN2003LV integrated circuit (IC), customers can reduce board space by up to 80 percent, while lowering power consumption and cost.

Key features and benefits of the ULN2003LV
-- High performance in noisy environments: Input resistor capacitor (RC) snubber greatly improves the driver performance in noisy operating conditions.
-- Channel grouping for higher current loads: Internal input pull-down resistor allows input logic to be tri-stated for greater efficiency at higher loads.
-- Lower power: Seven low-output impedance drivers minimize on-chip power dissipation, providing five times lower power consumption versus the competition.
-- Wider device compatibility: The relay's 1.8-V to 5-V CMOS logic input interface is compatible with a wider range of microcontrollers and other logic interfaces compared to the competition.
Availability, packaging and pricing
The ULN2003LV is available in 10-mm x 4-mm, 16-pin SOIC and 5.1-mm x 4.5-mm, 16-pin TSSOP packages. Suggested retail pricing in 100-unit quantities is $0.15.
