What is the input capacitance on the A and B inputs of AM26LS32A?
There is nothing shown in the equivalent circuit in the d-s, but I suppose there must be some pF capacitance to Vcc, to GND or differential from A to B; or possibly all three.
The reason for asking is that there is a TI app note (snla034b) about termination.
It includes a section about what it calls alternate-failsafe termination. It suggests series resistors Rc, Rd of value 4k7.
I was wondering how much delay this would introduce.
Kind regards,
Robert Taylor.
