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...

  • KH: Really? They are digital inputs driven by an MCU. The MCU GPIO probably has diode clamps and ESD protection. Have you experienced such failures? Please...
  • KH: Neither. Google "Marco Schweighauser’s 8-bit virtual Javascript CPU" and see the first result. Sounds more like a very limited feature toy CPU.
  • Alan: "8-bit x86 like CPU" - isn't that an 8080, or Z80?
  • Geoff: Is it still Sunday somewhere? If so, yes please.
