MAX13234EAUP+T

Drivers, Receivers, Transceivers Overview

The MAX13234EAUP+T is a dual RS-232 transceiver from the MAX13234E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3V to +5.5V supply and features an integrated low-voltage logic interface (VL) supporting voltages from 1.62V to VCC. The device provides two drivers and two receivers with a maximum guaranteed data rate of 250kbps. It incorporates AutoShutdown Plus technology, reducing supply current to 1µA when inputs are inactive for over 30 seconds. The component includes ±15kV HBM ESD protection and requires four external 0.1µF capacitors for charge pump operation. It functions within a temperature range of -40°C to +85°C and is housed in a 20-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption by entering a low-power shutdown mode when the RS-232 cable is disconnected or transmitter/receiver inputs remain inactive for more than 30 seconds.
• Integrated low-voltage logic interface allows direct connection to ASICs and microcontrollers operating at various logic levels without additional level shifting circuitry.
• Built-in dual charge-pump circuitry generates required RS-232 voltage levels using only four small external capacitors, minimizing board space requirements.

Drivers, Receivers, Transceivers Applications

• Telematics systems
• GPS modules
• Industrial control equipment
• Portable electronic devices
• Wireless communication modules

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EAUP' against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure the ordering code matches the exact pinout and electrical specifications required for the design. Cross-reference the datasheet revision date to confirm the validity of the technical parameters provided.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 interface is required with low standby power consumption. It is suitable for designs needing compatibility with low-voltage logic controllers while maintaining standard RS-232 signaling levels. Consider the 250kbps data rate limit; higher speed variants like the MAX13235E may be necessary for faster throughput requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13234E–MAX13237E family of high-speed RS-232 transceivers. The family shares common architectural features such as the AutoShutdown Plus feature and low-voltage interface but differs in channel count and maximum data rates. The MAX13234E specifically denotes the 2x2 configuration with a 250kbps speed rating.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13235EEUP+T offers identical pinout and packaging but supports up to 3Mbps data rates. Other family members like the MAX13236E provide single-channel configurations in smaller packages. Verify that any substitute maintains the same voltage ranges and ESD protection levels.
