MAX3318CDBRG4

Overview

The MAX3318CDBRG4 is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for portable applications requiring extended battery life. It operates within a supply voltage range of 2.25 V to 3 V and supports data rates up to 460 kbps. The device integrates two drivers and two receivers in a full-duplex configuration housed in a 20-SSOP package. It features a shutdown mode that reduces power consumption significantly. The component provides ESD protection rated at 15 kV according to IEC 61000-4-2 standards. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated ESD protection compliant with IEC 61000-4-2 standards for robust signal integrity
• Ultra-low power consumption with dedicated shutdown mode for battery-operated devices
• Single 2.5-V supply operation eliminates the need for external charge pumps or additional voltages

Applications

• Portable medical equipment requiring reliable serial communication
• Handheld terminals and mobile data collection devices
• Industrial control systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package variant matches the required PCB footprint for the 20-SSOP form factor. Ensure the temperature grade aligns with the intended operational environment specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits powered by a single 2.5-V source without access to higher voltage rails. It is suitable for applications needing moderate data speeds up to 460 kbps with minimal external passive components. Consider the thermal performance within the specified -40°C to +85°C range for harsh industrial deployments.

Part Context

This part belongs to the MAX3318 family of low-voltage RS-232 transceivers. It shares functional similarities with other members like the MAX3318IPWR but differs in packaging and specific environmental ratings. The CDBR suffix denotes a commercial temperature range variant in a tape-and-reel format, distinct from the IPWR TSSOP version.

Replacement Considerations

MAX3318CDBR serves as a parameter-equivalent alternative within the same product line. Verify compatibility regarding temperature ranges and package dimensions when substituting.
