7-channel relay and inductive load sink driver ICs

Tuesday, January 1st, 2013

Uwe tipped us to Texas Instruments' low power 7-channel relay and inductive load sink driver ICs: TI offers two rather new low power 1,8V & 3.3V & 5V 7-channel relay and inductive load sink driver ICs: - ULN2003LV (Output/Switching Voltage max. 8V - e.g. for 5V relays) - ULN2003V12 (Output/Switching...
