460 Kbps RS-232 link — single-channel full-duplex transceiver
The MAX3314ESA+ is a single-driver, single-receiver RS-232 transceiver from Analog Devices, rated for 460 Kbps data rate and full-duplex operation. That data rate covers standard UART speeds up to 460.8 kbaud — enough for legacy serial peripherals, industrial terminals, and debug ports where 115.2 kbaud is the floor and 921.6 kbaud is not needed. Supply range is ±4.75V to 5.25V, which means a single 5V rail alone will not work — the part expects a bipolar supply or an on-board charge-pump generating the negative rail.
Industrial temperature grade and 8-SOIC footprint
Operating temperature spans -40°C to 85°C, qualifying the part for factory automation, outdoor telecom cabinets, and engine-bay-adjacent electronics — not just climate-controlled office gear. The 8-SOIC package is a standard surface-mount footprint; the 0.154-inch body width fits a narrow PCB profile and is compatible with common 8-pin SOIC layouts. Mounting is surface-mount only; no through-hole variant is listed.
