Product details

RS-232 transceiver with 3 drivers and 5 receivers

It integrates three line drivers and five line receivers, a ratio that suits applications where the receive side needs more channels than the transmit side — common in multi-drop or monitor-heavy serial links. The part operates from a 3V to 5.5V supply, covering both 3.3V and 5V logic rails without a separate level shifter.

250 kbps data rate and 500 mV receiver hysteresis

Data rate is rated at 250 kbps.

Housed in a 28-TSSOP (4.40 mm width) with surface-mount footprint.

Frequently asked questions

Can the MAX3241ECUI+ operate at a 3.3V supply?

Yes, the supply voltage range is 3V to 5.5V, so 3.3V is within spec. The part will drive RS-232 levels from a 3.3V rail without external level translation.

What is the difference between the MAX3241ECUI+ and the MAX3241EAI+?

The MAX3241EAI+ is the same transceiver in a different package — the SSOP variant — while the MAX3241ECUI+ is in a TSSOP package. The electrical specifications (3/5 drivers/receivers, 250 kbps, 3V to 5.5V supply) are identical between the two.

What is the recommended alternative if the MAX3241ECUI+ is unavailable?

Within the same Maxim family, the MAX3241EAI+ (SSOP package) is electrically identical. For a pin-compatible alternative from a different manufacturer, check the SP3232E or MAX3232 families, but verify the driver/receiver count — the MAX3241 has a 3/5 ratio, while many alternatives offer 2/2.

Is the MAX3241ECUI+ RoHS compliant?

Yes, it is ROHS3 compliant, meaning it meets the EU RoHS directive without exemptions.
