Part Number: THVD1419 Other Parts Discussed in Thread: THVD1406 We are using this RS485 half duplex ic and we had a use case where we need to make RE_bar grounded and DE as High all the time irrespective of Data Transmission or Reception, when we are trying…
Part Number: THVD1419 Hello,
The THVD1419 consists of 1/8 UL transceivers, connecting up to 256 receivers to the bus is possible.
In system level, how could customer to do verification that their 1/8 UL system could support 256 receivers?
Do 256 loads…
Part Number: THVD1419 Other Parts Discussed in Thread: THVD1410 , Hello team,
I have a question about THVD1419 and THVD1410.
They have full failsafe functionality at RX side.
So external failsafe resistors (PU, PD) are not required, correct?
Regards,
I…
Part Number: THVD1419 Hello, does the THVD1419 /29 have a thermal shutdown that turns it on and off cyclically on overload? I have only found the reference that a shutdown takes place at 170°C. There is no further textual reference. How big is the hysteresis…
Part Number: SN65HVD72 Other Parts Discussed in Thread: THVD1419 Hi
I would like to use SN65HVD72 for an upcoming project, where we will have our main PCB, and the secondary PCB could be max 5 meters away.
We would like simple UART communication between…
You need fail-safe resistors on the bus if there is at least one receiver without fail-safe input. The SN75LBC184 does not have fail-safe inputs. (Consider a more modern device like the THVD1419/THVD1439.)
The fail-safe resistors must be able to generate…
For full duplex RS-485, if it has to be pin 2 pin compatible with SN65HVD33D, you can consider THVD1452D (50Mbps 3.3V/5V) or SN65HVD70D (400kbps 3.3V). Other than slower data rate, do you have other requirement on fault voltage or ESD?
The new RS-485 with…
