what is Maximum Junction Temperature of ADM485? 150℃?
I have a question about ADM485, RS-485 transceiver.
The datasheet says this device has fail-safe feature.
Could you be explain what is the fail safe feature of…
Our customer will use ADM485 and asks me about below.
Please let me know your advice.
ADM485 has receiver open fail safe.
So ADM485 has internal pull up resistor for fail safe.
If possible, could you give me about the value of internal pull…
I have a question ADM485 Propagation Delay.
If you have a Propagation Delay histogram data Driver and Receiver ,Please teach me.
There is properly working kit
I need to increase the PCB power supply for ATmega8 up to …
I have used an exception when using ADM485E communication. Some questions I would like to ask.
(1) ADM485E supports open fail safe function in RX mode in the datasheet, and the output is high level.
When all RS-485 driver is RX mode,the AB…
For MTBF calculations in accordance with MIL_HDBK_217F, I need the number of transistors (or MTBF/FIT) for the following devices:
Where it's possible to find this data? Can anyone help me?
is it safe to connect to RS-485 few ADM485 and ADM3485?
Some devices have Vcc=+3,3V and ICs ADM3485 are used for them,
some devices have Vcc=+5V and ADM485 are used.
1500 sets were produced, and about 80 sets could not be charged normally due to 485 IC problem,
The fault phenomena are as follows:
When the output current of power supply product reaches 30A or above,
Adm485 can not communicate, resulting in the output…
i have this circuit
and when i clear DE and RE pins output receive of adm485 make allot noise that make my MCU to RX overflow
is it normal or i should do something to fix it?
i forgot to put 100nF on VCC of it . cant it be the problem?
