MAX13433EESD+

Drivers, Receivers, Transceivers Overview

The MAX13433EESD+ is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates with a VCC supply voltage ranging from +3V to +5.5V and features an adjustable low-voltage logic interface (VL) supporting voltages from +1.62V to VCC. The device supports data transmission rates up to 16Mbps without slew-rate limiting. It includes one driver and one receiver, housed in a 14-pin SO package. Key electrical characteristics include a maximum shutdown supply current of 10µA and an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Adjustable low-voltage logic interface for direct interfacing with low-voltage ASICs or FPGAs
• Extended ESD protection on RS-485 I/O pins meeting IEC 61000-4-2 standards
• Hot-swap input structures on DE and RE pins to prevent false transitions during insertion
• 1/8-unit load receiver input impedance allowing up to 256 transceivers on the bus

Drivers, Receivers, Transceivers Applications

• Industrial Control Systems
• Motor Control
• HVAC Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead-free status. Ensure that the VL pin is properly decoupled with a ceramic capacitor close to the input for optimal performance. Confirm compatibility with system voltage levels before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed full-duplex communication is required alongside low-voltage logic compatibility. The absence of slew-rate limiting distinguishes it from the MAX13432E variant. Consider the 14-pin SO package constraints regarding thermal dissipation and board space requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13430E–MAX13433E family of RS-485 transceivers. While the MAX13432E offers similar functionality with reduced slew rates for lower EMI at 500kbps, the MAX13433E provides unrestricted driver slew rates to support data rates up to 16Mbps.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13432EESD+ serves as a functional alternative if reduced electromagnetic interference is prioritized over maximum speed, though it is limited to 500kbps due to enhanced slew-rate limiting.
