The 1 Mbps data rate is comfortably above the 115.2 kbps that most legacy equipment uses, so you get margin for higher-speed UART links without pushing the edge. ## Supply flexibility and temperature range It runs from a single 3V to 5.5V rail, so you can drop it onto a 3.3V or 5V logic bus without a second regulator. ## Package and footprint realities The 36-WFQFN with exposed pad — the supplier device package is 36-TQFN 6x6 mm. That exposed paddle needs a thermal via array under the pad to pull heat into the ground plane. The 0.5 mm pitch demands a soldermask-defined pad and a stencil aperture that doesn't bridge; a rework station with hot air is the right tool if you're hand-assembling prototypes. ## Active production and sourcing posture Analog Devices is the sole source; there is no official second-source cross-reference. The part is RoHS non-compliant, so if your BOM requires RoHS exemption documentation, flag that at quote time.","metaTitle":"MAX3245EETX RS-232 Transceiver 3/5 Drivers/Receivers 1Mbps","metaDescription":"MAX3245EETX RS-232 transceiver from Analog Devices. 3 drivers, 5 receivers, 1 Mbps, 3V to 5.5V supply, industrial temp.
