RS-232 transceiver with 3 drivers and 5 receivers
The Maxim Integrated MAX3241ECUI+ is a full-duplex RS-232 transceiver in a 28-TSSOP package, handling serial communication between a UART and an RS-232 line. 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. The 500 mV receiver hysteresis provides noise immunity on the incoming line.
Package and temperature range
Housed in a 28-TSSOP (4.40 mm width) with surface-mount footprint. The operating temperature range is 0°C to 70°C.
Lifecycle and compliance
The MAX3241ECUI+ is listed as Active with no end-of-life notice, and it is ROHS3 compliant — no exemptions that would complicate EU or global BOM compliance.
