Data rate is 20 Mbps over a 4.5 V to 5.5 V supply, with 15 mV receiver hysteresis. ## Supply rail and logic compatibility This part runs on a 5 V nominal supply (4.5 V to 5.5 V range). It is not a 3.3 V logic-compatible transceiver — if your UART or controller operates at 3.3 V, you will need level translation on the driver input and receiver output pins. The 15 mV receiver hysteresis helps with noise immunity on differential pairs, but the supply rail is the hard constraint for BOM fit. ## Package and thermal management 14-TSSOP with exposed pad (14-TSSOP-EP) requires a thermal-land pattern on the PCB for heat sinking. The exposed paddle must be soldered to a copper plane. ## Lifecycle and compliance It is ROHS3 compliant, so it meets the current EU restriction directive without exemption.","metaTitle":"MAX13451EAUD+T RS-485/RS-422 Transceiver, 20 Mbps","metaDescription":"MAX13451EAUD+T half-duplex RS-485/RS-422 transceiver from Analog Devices. 20 Mbps data rate, 4.5V–5.5V supply, -40°C to +125°C.
