Product details

RS-232 transceiver with 1 Mbps throughput and wide supply tolerance

It supports data rates up to 1 Mbps, which is sufficient for legacy serial ports and many industrial point-to-point links where the bus capacitance and cable length are within the RS-232 standard. The supply voltage range of 3V to 5.5V allows direct connection to either 3.3V or 5V logic rails without an intermediate regulator, simplifying the power tree in mixed-voltage designs.

Active production — no obsolescence pressure

It is ROHS3 compliant, meeting current European material restrictions.

Frequently asked questions

Is the TRSF3232EIDW a direct replacement for the TRSF3232E?

The TRSF3232EIDW shares the same base function and pinout as the TRSF3232E, but the 'IDW' suffix indicates the 16-SOIC (0.295", 7.50mm width) package variant. Verify the package footprint on your board before substituting; the electrical specifications are equivalent.

Can I use the TRSF3232EIDW as a replacement for the MAX3232?

The TRSF3232EIDW is functionally similar to the MAX3232 — both are 2/2 RS-232 transceivers with a 3V to 5.5V supply range. However, pin assignments and receiver hysteresis may differ. Compare the datasheet pinout and confirm the PCB layout before substituting.
