NTB0102 unused pin termination

[andy_kim]

Hello,

I'd like to apply NTB0102 voltage level translator instead of 74AVC2T45 for SPDIF signal line.

Let me attache the picture of the circuit for your refer.

As you might know, NTB0102 is 2-bit voltage level translator.

How should I do termination for the 1-bit pin which is not used? Floating or Connecting to GND?

Hello Andy,

The A and B sides of an unused I/O pair must be held in the same state, both at VCCI or both at GND. I would recommend to connect the unused I/O pair to GND.

With Best Regards,

Jozef
