Product details

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

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.

Frequently asked questions

What is the MAX3314ESA+ data rate?

The specified data rate is 460 Kbps. This supports standard UART baud rates up to 460.8 kbaud, covering most RS-232 point-to-point links in industrial and embedded systems.

What is the closest pin-compatible alternative to the MAX3314ESA+?

Within the same RS-232 transceiver class, parts like the MAX3232 or MAX3221 share the 8-SOIC footprint and similar supply range, but the MAX3314ESA+ is specified at 460 Kbps with 500 mV hysteresis. Confirm pinout and driver/receiver count against your schematic before substituting — the MAX3314ESA+ is a 1/1 device, while some siblings offer 2/2 or 3/5 configurations.
