Hello,
I'm trying to figure out a basic circuit to wire up a 2 coil latching DPDT relay to switch a line-level stereo audio signal, specifically a Panasonic TQ2SA-L2. Datasheet here: https://www.alliedelec.com/m/d/6ec7cf7d6911bb3ba06b633c7af273e6.pdf. My hope is that I can use a single relay IC to turn each stereo input "on" or "off" (basically whether that input gets routed to the amplifier stage.) I understand that I need a diode to protect against voltage spikes when the relay is switched, but I'm not clear which pins the diode would be between.
I guess my biggest problem is that I'm not clear on the operation of the IC and what each pin is for. It looks like pins 1-5 function as one switch and 6-10 function as a separate switch? Pins 1 and 5 are for control. 3 is the signal source and 2 and 4 are the signal outputs?
Sorry for the remedial-level question, I've been reading threads on other 2 coil latching relays, but I can't tell how they apply to my chip.
Thanks,
Tom
