Product details

The MAX3322EEUP+T: The 250 kbps data rate is the practical ceiling for this part — above that, the slew-rate-limited output stage on the RS-232 line drivers cannot maintain the ±5V swing into the specified load capacitance, so the eye diagram closes. For a UART link running 115.2 kbps or 230.4 kbps, this part has margin; for a 1 Mbps application, it does not.

Supply rails and temperature grade — where this transceiver fits on the board

The 350 mV receiver hysteresis filters out noise on long cable runs — a 30-foot RS-232 cable in an electrically noisy environment picks up common-mode transients that a 200 mV hysteresis receiver would toggle on; this part's 350 mV window rejects those edges.

Frequently asked questions

What is the data rate of MAX3322EEUP+T?

The MAX3322EEUP+T is rated for a maximum data rate of 250 kbps. This is the ceiling for the RS-232 line drivers under the specified load; practical UART rates of 115.2 kbps or 230.4 kbps run with margin.

Is MAX3322EEUP+T RoHS compliant?

Yes, it is ROHS3 compliant per the manufacturer's lifecycle data.

Can I use MAX3322EEUP+T as a replacement for MAX3222EEUP+T?

The MAX3322EEUP+T and MAX3222EEUP+T share the same 20-TSSOP package and 2/2 driver/receiver count, but their electrical specifications differ. The MAX3322EEUP+T is rated for 250 kbps and 3V–5.5V supply; the MAX3222EEUP+T has a different data rate and supply range. Confirm the BOM's parametric requirements before substituting — the pinout is identical, but the timing and drive strength may not match.
