MAX13234EETP+

Drivers, Receivers, Transceivers Overview

The MAX13234EETP+ is a dual-driver, dual-receiver RS-232 transceiver in a 20-pin TQFN-EP package. It supports data rates up to 250kbps and operates from a +3V to +5.5V supply voltage. The device features an integrated low-voltage logic interface (VL) ranging from 1.62V to VCC for direct connection to microcontrollers. It includes AutoShutdown Plus technology that reduces supply current to 1µA when the cable is disconnected or inputs are inactive for over 30 seconds. Internal charge pumps generate ±5.5V using four external 0.1µF capacitors.

Drivers, Receivers, Transceivers Feature Summary

• AutoShutdown Plus functionality automatically enters low-power shutdown mode after 30 seconds of inactivity to minimize power consumption.
• Integrated low-voltage logic interface allows seamless compatibility with ASICs and microcontrollers operating at various logic levels.
• Built-in ±15kV Human Body Model ESD protection ensures robust performance during handling and assembly without external components.

Drivers, Receivers, Transceivers Applications

• Telematics systems
• GPS navigation modules
• Industrial control equipment
• Point-of-sale (POS) terminals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure the component matches the required pin configuration and thermal pad specifications for your PCB layout. Cross-reference the datasheet revision date to confirm the electrical characteristics align with your design requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required within a compact surface-mount footprint. It is suitable for designs needing low standby power through automatic shutdown features. Verify that the application load capacitance does not exceed the limits specified for the 250kbps data rate to ensure signal integrity and proper operation across the full temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1323xE family of high-speed RS-232 transceivers manufactured by Analog Devices Inc./Maxim Integrated. The family shares common architectural features such as the dual charge pump and low-voltage logic interface but varies in driver/receiver counts and maximum data rates. The 'E' suffix indicates extended industrial temperature range capability, while the 'TQP+' denotes the specific 20-pin TQFN-EP package variant.
