Part Number: TRS3238E Tool/software: I have used TRS3238EIPWR as RS232 transceiver in my design and while bring up all channels working except RIN1. The RIN1 is getting RS232 Level signal but its not reflected at ROUT1 or ROUT1B. I even changed IC with…
Hello Ronald, Thank you for your reply.
I want to drive this relay.
en-g5v_1.pdf As for this relay, 30mA is necessary for 5V.
Do you have a good solution?
Best regards, Dice-K
Other Parts Discussed in Thread: TRS3238E , MAX3238E , TRS3237E As far as I can tell, when the TRS3238E goes into powerdown mode, it fails to propagate the start bit from RIN* to ROUT*:
Tx Rx ROUT* (not including the stop bit)

Hello Kazuya-san,
No, this part number was not tested against IEC1004-2 to my knowledge. It could be used in applications with this requirement if protection could be implemented externally via a TVS diode. Here is an article discussing how to select…
Hi Donald,
The MAX3238E would be a pin-for-pin replacement to TRSF3238E with substantially lower output slew rate (since it was designed for maximum baud rates of 250 kbps). Based on the waveform you described (with fast rise times and slow decay)…
Nicky,
I don't recommend signal switching on the DB9 connect. Use a RS-232 device and RS-485 device with disables.
For RS-232 device try TRS3238E or faster TRSF3238E. I assume that this connect to a computer (DTE) so I made the RS-232 side DCU. I…
