MAX13448EESD+

Drivers, Receivers, Transceivers Overview

The MAX13448EESD+ is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +3.0V to +5.5V supply voltage and features inputs and outputs fault protected up to ±80V with respect to ground. The device supports data rates up to 500kbps at +5V and 250kbps at +3.3V, utilizing slew-rate limiting to minimize EMI. It includes true fail-safe circuitry, hot-swap capability on the DE pin, and ±8kV Human Body Model ESD protection. The receiver input impedance is 1/8-unit load, allowing up to 256 transceivers on the bus. It is available in a 14-pin SO package and operates over an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13448E series of RS-485 interface ICs. It is part of Maxim Integrated's portfolio of robust communication transceivers designed for industrial environments. The 'ESD+' suffix denotes a lead-free package compliant with environmental standards.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must maintain ±80V fault protection and full-duplex operation. Verify pinout compatibility with the 14-pin SO package. Check that substitute components support the same data rate and supply voltage requirements.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the MAX13448E?

The device supports data rates up to 500kbps with a +5V supply and 250kbps with a +3.3V supply.

How does the fail-safe feature work?

The true fail-safe circuitry guarantees a logic-high receiver output when the receiver inputs are open, shorted, or connected to a terminated line with all drivers disabled.

What is the purpose of the hot-swap capability?

The hot-swap input structure prevents disturbances on the differential signal lines and eliminates false transitions when a circuit board is plugged into a powered backplane.
