7-channel relay driver

3 October 2012 Analogue, Mixed Signal, LSI

Texas Instruments has introduced a 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 replaces a handful of discrete components with a single device to drive lower voltages for data relays and rails within telecommunications equipment. An input resistor capacitor (RC) snubber greatly improves the driver performance in noisy operating conditions, while an internal input pull-down resistor allows input logic to be tri-stated for greater efficiency at higher loads. The chip is available in 10 x 4 mm, 16-pin SOIC and 5,1 x 4,5 mm, 16-pin TSSOP packages.
