TRSF3221E: product recommendation

Rhea Gao

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~

The TRS3221E would be slower and cheaper.

RS-232 transceivers have a low power consumption only when they are powered down. The 3221's auto-powerdown function deactivates its own driver when its receiver is not connected to an active driver.

Clemens,

Thanks for your help, as always.

Rhea,

An engineer from TI will comment further by the end of the week as well. Thanks for your patience.

Hi Rhea,

Was Clemen's response enough to solve your recommendation or do you need further assistance? If so, please also provide the amount of transmitters and receivers you require, any ESD requirements needed, and max data rate you need to support.
