The only transceiver that can run with a 1.8 V supply is the TRS3122E, with 2/2 drivers/receivers.
If you have a 3.3 V or 5 V supply, you can also use the TRS3227/MAX3227, or TRS3227E/MAX3227E with better ESD protection.
If you have 1.8 V control signals, then you cannot use a 3.3 V device like the TRSF3223E.
(Or you would need to route the control signals through a translator. Do you actually need two RX and two TX signals? If you need only 1+1, then you could use the…
Gilad,
Thank you for your question.
Please consider the TRS3227E RS-232 tranceiver (1Mbps, 3.3V-5V supply range, single channel, with Enable). The datasheet may be found here:
TRS3227E DS
For your UART inquiry, do you have a preference for number of…
Hello, Ron Michallick:
Did you means:
If I use powerdown function, when TRS3227E in powerdown mode, I must first send a unuse data, then wait a while or read the READY pin, then I can send my own data? And this unuse data may cause recive a unknow…
