MAX2023ETX+

Overview

The MAX2023ETX+ is a dual RS-232 transceiver from Maxim Integrated, designed for portable applications. It operates from a single 3.0V to 5.5V supply and includes charge pumps to generate V+ and V- voltages without external inductors. The device features two drivers and two receivers, with ESD protection exceeding ±15kV according to the Human Body Model. It supports data rates up to 120kbps and is available in an 8-pin TSSOP package.

Feature Summary

Integrated charge pump eliminates need for external inductors or transformers
Single-supply operation compatible with 3.0V to 5.5V power sources
High ESD protection ratings ensure robustness in harsh environments
Compact 8-pin TSSOP package suitable for space-constrained designs

Applications

Portable computers and notebooks
Handheld devices and PDAs
Modems and communication equipment
Industrial control systems requiring RS-232 connectivity

Procurement Notes

Verify the suffix 'ETX+' indicates lead-free compliance and RoHS adherence. Confirm the package type matches your PCB footprint requirements. Ensure voltage levels align with system specifications before procurement.

Selection Notes

Choose this component when space constraints limit the use of larger packages or external charge pump components. It is ideal for battery-powered devices due to its low standby current and single-supply capability. Compare pinouts with legacy parts if replacing existing designs.

Part Context

Part of Maxim's MAX202x family of RS-232 transceivers. Designed for mobile and handheld applications where size and power efficiency are critical. Offers improved performance over earlier generations with enhanced ESD protection and lower power consumption.
