Other Parts Discussed in Thread: SN65HVD3088E, SN65HVD3085E
Hi team,
I have a few questions regarding SN65HVD308xE. As a quick note, I've been referencing Section 6.7, Figure 2 and Figure 5 of the datasheet and this e2e thread.
- If there are two termination resistors on each end of the bus, and each is 120Ohm, should I use RL = 120Ohm in Figure 5? Termination is 120Ohm, but with these in parallel and the effective resistance being 60Ohm, I just want to make sure I'm looking at the right numbers.
- Can SN65HVD3085E & SN65HVD3088E run at 19.2kbps? I believe the answer is "yes," so would there be any drawbacks for using them at such low data rates?
- I'm trying to understand the Bus Input Currents better. My understanding is that this is a current drawn per transceiver that you multiply by however many transceivers are on the line to get your total. This total is the amount of current needed to be driven from a transceiver onto the bus in order to have the signal reach the transceiver it is talking to considering the loads from all the other listening transceivers on that same bus. This total is added with others to find the total current draw on a slave transceiver that is in use. Do you have any more documentation on this subject?
Thanks,
Brian
