MAX33048EASA+T

Overview

The MAX33048EASA+T is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 20 Mb/s. The device features integrated ESD protection rated at 40 kV, ensuring robust performance in harsh environments. It includes one driver and one receiver housed in an SOIC-8 surface-mount package. Operating temperatures span from -40°C to +125°C, with a typical quiescent current of 6 mA. Propagation delays are specified at 40 ns for the driver and 75 ns for the receiver.

Feature Summary

• Full-duplex communication capability supporting simultaneous transmission and reception on separate lines.
• High electrostatic discharge protection rated at 40 kV to safeguard against transient events.
• Wide operating temperature range suitable for industrial and automotive applications.

Applications

• Industrial automation systems requiring reliable serial communication.
• Building automation networks utilizing RS-485 or RS-422 protocols.
• Process control instrumentation in harsh electromagnetic environments.

Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm the suffix +T indicates tape-and-reel packaging and that the part meets RoHS standards. Cross-reference the manufacturer part number with official datasheets to ensure compatibility with system requirements before procurement.

Selection Notes

Select this component when full-duplex operation is required alongside high ESD immunity. Compare propagation delay specifications against system timing constraints. Ensure the SOIC-8 package fits the PCB layout. Verify that the 3 V to 5.5 V supply range aligns with the target application's power architecture.

Part Context

This part belongs to the MAX3304x series of high-speed, low-power transceivers. It shares functional similarities with other devices in the family but differs in duplex mode and specific protection ratings. The MAX33045EASA+T offers half-duplex operation, while the MAX33048EASA+T provides full-duplex functionality within the same package and voltage parameters.

Replacement Considerations

The MAX33045EASA+T serves as a related alternative but provides half-duplex rather than full-duplex operation. Verify interface requirements before substitution. No other direct pin-to-pin replacements with identical full-duplex specifications were identified in the provided documentation.
