Part Number: SN75LBC176 Other Parts Discussed in Thread: SN65LBC176 , Hi team,
Why is there a difference in the minimum differential output between SN75LBC176 and SN65LBC176? Is it the same if the temperature range is 0~70℃?
Sincerely. Ryu
Part Number: SN75LBC176 Other Parts Discussed in Thread: THVD1420 , THVD1520 Hi team,
I have a question of matching resistance between output A and B of RS485 transceiver ‘SN75LBC176’. If we do not use the value of 110 Ohm, which is shown in the datasheet…
Part Number: SN75LBC176 Other Parts Discussed in Thread: THVD1550 , THVD1500 Hello,
For a design in production, we use a two SN75LBC176 connected to a micro-processor for a RS422 communication link (UART). One component is configured in TX mode only…
Part Number: SN75LBC176A Other Parts Discussed in Thread: SN75LBC176 Hello,
We are currently using a SN75LBC176 but we want to change it due to its' power supply voltage. We are looking forward to use a 3.3V device. I would appreciate any suggestion…
Fax,
Unfortunately there is no EVM available for SN65C1168 so far. If using a bread board is not an option, you might use two single channel half duplex RS485 EVM for system evaluation. Single channel RS485 transceivers have very similar electrical…
Hi Karthik,
thank you for updating me, it gives me a better understanding of your application.
In the specific picture that I posted, the TVS diodes are CDSOT23-SM712 by Bourns; you can find the full BOM on table 7 of the datasheet of THVD1552. It…
Hi Roy,
1. The failsafe network contains in your case R1801 and R1812 they pull up the the A and B BUS lines to insure that always a defined voltage is provided to the bus. You can find mor information (Page 10,11 and 12) here:

Hi Kaji,
the current source red circle in the diagram is used to mimic the leakage circuit that generates the receiver fail-safe threshold. The internal fail safe is offering fail safe for open-line cases. But you can not use this feature when you are…
This spreadsheet tool makes it easy to look up what the recommended pin to pin capable RS-485 transceivers to replace old TI RS-485 transceivers.
