Part Number: TRSF3232

How should I process unused pins?

unuse pin: DIN2, DOUT2, RIN2, ROUT2

Is it enough to connect DIN and RIN to GND?

Is a pull-up / pull-down resistor necessary?

Best Regards.

Hi Sopatopa,

The outputs (DOUT and ROUT) can be left disconnected. The RIN inputs can be left floating as well and will be pulled low internally. The DIN inputs should be pulled to a known-state (high or low) either by using pull-up/pull-down resistors or grounding the pin.

Regards,
Max
