  • SN65HVD75: SN65HVD75

    Part Number: SN65HVD75 Tool/software: Hi, I am using SN65HVD75DGKR devices for RS-485 communication, some times I see different resistance on the A and B inputs referred to ground (pin 5) such as 220K and 1M. I tend to think that 220K is the internal…

  • SN65HVD75: Application issues.

    Part Number: SN65HVD75 Tool/software: Hi Team, Using SN65HVD75DGKR, The schematic diagram is shown in the following figure, 1. 2, 3, and 4 pins are directly connected to the MCU, while pins 6 and 7 (A and B) communicate with the outside through a connector…

  • SN65HVD75: Exposed Pad of the VSON Package of the sn65HVD75

    Resolved
    Part Number: SN65HVD75 Hey Guys, I have a very trivial question. I am using a SN65HVD75 in my project with a VSON-8 Package. While I studied the data sheet I noticed that it is not explicitly described to connect the thermal pad to GND. I assume that…

  • RE: SN65HVD75: SN65HVD75DR

    Hi all Based on your measurement suggestion, here's what I've measured before. It seems this SN65HVD75 still cannot transmit TX signal to A-B bus. Now our MCU can get RX signal from SN65HVD75, but SN65HVD75 can't transfer TX properly. Any comments…

  • SN65HVD75: low pin count control with DE/RE# and R/D shorted together

    Resolved
    Part Number: SN65HVD75 Hello, I would try a pin reduced approach to sharing a signal for DE/RE# and another for D/R. Provided that controller will have to change direction of port for D/R signal with proper timing avoiding contention with R, could it…
