Part Number: TXB0104
Other Parts Discussed in Thread: TXU0104, TXU0204

I'm planning to use TXB0104 level translator for converting 2.15V, 2.8V RS-232 signals to be compatible with U209-000-R (USB-A to RS232 (DB9) Serial Adapter Cable).

Data Rate - 115200.

Please let me know can i use it for above application.

Also I'm planning to use TXU0104 level translator to convert 5V input to 1.8V, 2.15V, 2.8V, 3.1V etc. Please let me know whether VIH,VOH are compatible.

For unidirectional signals, you should use a TXU converter like the TXU0104 or TXU0204.

TXU translators support all these I/O voltages, as long as the supply voltages match.

Please provide the .CIR, .TSM model of TXU0104 for simulation. I'm unable to run IBIS, Hspice model in TINA.

Hi Girish,

Unfortunately there aren't other models as just the IBIS model is in the product folder, thanks.

Best Regards,

Michael.

Hi Michael,

Thank u for the reply.

I'm planning to use TXU0304PWR, TXU0202DCUR for voltage conversion as shown below. Can below IC be use for voltage conversion 3.1,2.8, 2.15 which are not TTL, CMOS level.

TXU0304PWR

TXU0202DCUR

Thanks,
