DS26F31MQML-SP: RS-422 Cold Spare I/O

Sam Stratton

Part Number: DS26F31MQML-SP
Other Parts Discussed in Thread: DS26F32MQML-SP,

I would like to know if the DS26F31MQML-SP and DS26F32MQML-SP have 'Cold Spare' I/O? Cold Spare simply means the I/O's are high impedance when Vcc is below a certain value or 0V.

Hi Sam,

Please note that datasheets for the 31 states that the output won't load the line when Vcc=0 and for the 32 that the inputs are high impedance, independent of Vcc.

Thank you very much Kirby. I thought as much about that statement. Still, for us space geeks, I would recommend stating it closer to how I did for that feature. Not sure where the term 'Cold Spare' came from, but it is very common in the space community.

Thank you for you input. Note that on newer datasheets for space grade products, we are including "cold sparing" where appropriate.
