MAX13236EETE+T

Drivers, Receivers, Transceivers Overview

The MAX13236EETE+T is a single-channel RS-232 transceiver from the MAX1323x family, designed for low-voltage interface applications. It operates on a supply voltage range of +3V to +5.5V with a logic supply (VL) between +1.62V and VCC. The device supports data rates up to 250kbps under worst-case load conditions (RL = 3kΩ, CL = 1000pF). It features AutoShutdown Plus technology, reducing supply current to 1µA when inputs are inactive for over 30 seconds. Integrated charge pumps require four external 0.1µF capacitors for operation. The component includes ±15kV HBM ESD protection and is housed in a 16-pin TQFN-EP 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 inputs remain inactive for more than 30 seconds.
• Integrated dual charge-pump circuitry generates internal positive and negative voltages using only four external capacitors, eliminating the need for bipolar supplies.
• Robust electrostatic discharge protection rated at ±15kV Human Body Model and IEC 61000-4-2 standards ensures reliability during handling and assembly without latchup.
• Flexible low-voltage logic interface allows direct connection to ASICs and microcontrollers operating at various logic levels via the separate VL pin.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EETE+' against the manufacturer's official documentation to confirm the exact package type, temperature grade, and lead-free status. Ensure that the ordering information matches the required data rate specifications within the MAX1323x family, as variants differ significantly in performance capabilities.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single full-duplex channel is required for RS-232 communication in space-constrained designs. It is suitable for systems needing automatic power management through AutoShutdown Plus. Verify that the application load capacitance does not exceed the limits specified for the 250kbps data rate to ensure signal integrity.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13234E–MAX13237E family of high-speed RS-232 transceivers. While sharing similar architecture and features, other members like the MAX13237E offer higher data rates up to 3Mbps. The MAX13236E specifically targets applications requiring moderate speed with enhanced power efficiency and low-voltage compatibility.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13237EETE+ offers identical pinout and packaging but supports data rates up to 3Mbps. Designers may substitute this part if higher throughput is needed without altering the board layout. Ensure that the increased slew rate of the replacement does not cause signal integrity issues in existing traces.
