Part Number: SN65HVS885 I cannot find information on whether to terminate REx connection for LED output or left unconnected if I dont want to drive LEDs using REx pins of HVS885.
Do I need to reconsider my RLIM value if I terminate REx output to GND? …
Hi Nir,
Thanks for the reply. I used the SN65HVS883 in previous products, but after looking at the other versions, the SN65HVS885 actually does exactly what I'm looking for. It's supplied only by 5V and the 24V pin is now NC. So now I know what…
Hey Tcheng, Jimmy So the issue i'm seeing here is when you have the REx high. Here's a simplified block diagram of a single channel to help explain the issue better: So you see that the return current (through the limiter circuit) goes to a switch…

1. HVS885 IPx and REx relationship? I will take a ground resistance to generate a square wave, input to Mcu to do counter. Explain:
a. In order to have an output waveform on REx, there will be a R connect to group . It will be…

I have a 24V motor PWM or PTO signal input.
Hot to Use SN65Hvs885 receiver PWM or PTO signal and pass to F280049CPMS GPIO eQEP-1 ?
Now I will use SN74HC595 to pass signal but I not sure this…
Part Number: SN65HVS885 If there is a voltage of 24 volts on one input(like IP0) and a ground on another(like IP1 or the rest of the pins), would these pins be able to handle this kind of function if the ground for the chip is accidentally disconnected…
Part Number: SN65HVS885 Hello,
Do the RE pins on the device need to be left as no connects or shorted to ground then they are not attached to LEDs?

Part Number: SN65HVS885 Other Parts Discussed in Thread: TIC12400 , ISO1212 The SN65HVS885 would have been the ideal solution for my application, had it had Open circuit Fault detection inbuilt into it.
Can you please suggest another part having the functionality…
