MAX13237EETE+

Drivers, Receivers, Transceivers Overview

The MAX13237EETE+ is a single-driver, single-receiver RS-232 transceiver from the MAX1323x family. It supports data rates up to 3Mbps and operates on a VCC supply of +3V to +5.5V with a logic supply (VL) ranging from +1.62V to VCC. The device features AutoShutdown Plus technology, reducing supply current to 1µA when inputs are inactive for over 30 seconds. It includes integrated dual charge pumps requiring four external capacitors and provides ±15kV HBM ESD protection on driver outputs and receiver inputs. The component is housed in a 16-pin TQFN-EP package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption by shutting down internal circuitry after 30 seconds of input inactivity.
• Integrated low-voltage logic interface allows direct connection to microcontrollers and ASICs operating at various voltage levels.
• Built-in dual charge pump generates required RS-232 voltages using only four external capacitors.
• High-level electrostatic discharge protection ensures robustness against human body model and IEC contact discharges.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'EETE+' corresponds to the specific 16-pin TQFN-EP package variant. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the procurement channel sources genuine Analog Devices or Maxim Integrated components to guarantee electrical characteristics match the official datasheet specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this part when a single full-duplex RS-232 channel is required alongside high-speed 3Mbps performance. It is suitable for designs needing flexible logic level interfacing via the separate VL pin. Consider alternatives like the MAX13236E if a lower 250kbps rate is sufficient, or the MAX13235E if two channels are needed.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13234E–MAX13237E family of high-speed RS-232 transceivers. While sharing core architecture with the MAX13234E through MAX13236E, it is distinguished by its 3Mbps maximum data rate capability and its 1x1 configuration. It shares the same space-saving TQFN packaging and low-power shutdown features found across the series.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13236E offers identical packaging and features but is limited to a 250kbps data rate. For applications requiring two channels, the MAX13235E provides a 2x2 configuration with 3Mbps support. Verify that any replacement maintains the 16-pin TQFN-EP footprint and compatible thermal resistance values.
