It converts logic-level UART signals to RS-232 voltage levels for serial communication over cables up to about 15 meters, depending on cable capacitance and data rate. Data rate is rated at 460 kbps, which covers common UART speeds up to 460.8 kbaud — enough for industrial terminals, PLC programming ports, and embedded debug consoles. The 500 mV receiver hysteresis provides noise margin on the receive line, useful in electrically noisy factory-floor environments. Supply voltage range is ±4.75 V to 5.25 V, so it runs from a single 5 V rail with an internal charge-pump generating the RS-232 bipolar levels. No external ±12 V supply needed.
Package, footprint, and temperature grade
Housed in an 8-lead uMAX/uSOP package, which is the same footprint as a standard 8-MSOP or 8-TSSOP — 3.00 mm body width, 0.65 mm pin pitch. The small outline saves board space but demands careful soldering: the 0.65 mm pitch is fine enough that a stencil aperture reduction is recommended for consistent paste volume. Not automotive-qualified, but fine for outdoor telecom cabinets, HVAC controllers, and test equipment that stays above the freezing point.
Production status and sourcing posture
Analog Devices continues to manufacture this part, so it is a safe BOM line for new designs and ongoing production. For volume orders, reel or tape-and-reel variants may be available — confirm at quote time. Pricing and lead time are confirmed per RFQ against your target quantity.
