Part Number: TRSF3221E Other Parts Discussed in Thread: TRSF3223E Tool/software: Hi Team, We are using TRSF3221EIRGTR - RS232 Transceiver in our designs. we are using UART to RS-232 which involves TX and Rx in this IC. As we need to deploy flow controls…
Part Number: TRSF3221E Tool/software: Hi team,
We are using RS232 Transceiver ( UART <-> RS232 ) with TRSF3221EIRG IC. For this one do we need to give the 10K pull up to VCC for DIN ( TX of UART ) and ROUT ( RX of UART ). As we are referring the…
Part Number: TRSF3221E Other Parts Discussed in Thread: TMUX7234
Tool/software:
Hello,
I had asked a question previously about using the TMUX7234 to switch RS232 signal lines. After doing more research I was able to come up with a design and would…
Part Number: TRSF3221E Other Parts Discussed in Thread: TRS3221E Hi,
Please help to recommend a product for battery power supply, hoping that the static power consumption is small, the speed requirement is very low, and the package is also small.
Thank…
Part Number: TRSF3221E
Hi,
I am considering using the TRSF3221E, but I need a short protection on its output.
The TRSF3221E typical short current is +/-35mA.
Is that mean I need to add series resistor of ~150ohm?
Or should I use additional protection IC…
Part Number: TRSF3221E Hi,
Before I was using MAX3221EIPWR, my specified baud rate is 921600 and transmit delay 250 msec/line. I am getting junk values as output. But when I probe the input values directly I get proper values at baud rate 921600 and transmit…
Part Number: TRSF3221E Hello, back again ...
in the data sheet on page 6 I found the following values for the "Output resistance": MIN: 300 TYP: 10M Unit: Ohm @Vo=+-2V What does 10M mean (M=Mega ...) i am confused ... Under short circuit condition the…
Part Number: TRSF3221E Hello, The device has an internal voltage doubler / multiplier.
Which switching-frequency is used?
Is there an application note to avoid EMC interference radiation by the voltage doubler or are the capacitors sufficient?

Part Number: TRSF3221E We are using the RS232 driver TRSF3221ECPW.
During start up, the output drivers (DOUT) shall be on high-Z. To do this, we want slow up the nFORCEOFF pin with a RC (resistor capacitor Network) (for example 47kOhm and 4.7uF). So th…
The MAX3223E supports 500 kbaud and has auto-powerdown and good ESD protection.
Similar 1+1 devices are the MAX3221E/TRS3221E (250 kbaud) or TRSF3221E (1000 kbaud).
