MAX13089EEPD+

Drivers, Receivers, Transceivers Overview

The MAX13089EEPD+ is a +5.0V RS-485 transceiver featuring one driver and one receiver in a 14-pin PDIP package. It supports data rates of 250kbps, 500kbps, and 16Mbps via pin-selectable slew-rate limiting. The device includes ±15kV ESD protection on I/O pins, true fail-safe circuitry, and hot-swap capability on DE and RE inputs. Supply voltage ranges from 4.5V to 5.5V with a typical supply current of 1.2mA. It operates over an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Pin-selectable full-duplex or half-duplex operation
• Programmable transmitter and receiver output phase control
• Hot-swap input structures prevent false bus transitions during power-up

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Profibus Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix EE indicates the -40°C to +85°C temperature grade and PD denotes the 14-pin plastic DIP package. Confirm RoHS compliance status for lead-free requirements. Ensure the ordering code matches the exact pin configuration and thermal specifications required for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when variable transmission speeds are required within a single design. Use the SRL pin to configure data rates between 250kbps, 500kbps, and 16Mbps. Utilize the H/F pin for duplex mode selection and TXP/RXP pins to correct twisted-pair wiring reversals without hardware changes.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13080E–MAX13089E family of high-speed RS-485 transceivers. Unlike fixed-speed variants in the series, the MAX13089E offers flexible configuration options for both communication speed and duplex mode through dedicated control pins.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes include other members of the MAX13080E family such as the MAX13086E or MAX13087E if fixed 16Mbps operation is sufficient. Verify package compatibility and temperature ratings when substituting.

Drivers, Receivers, Transceivers FAQ

How is the data rate configured on the MAX13089E?

The data rate is selected by driving the SRL (Slew-Rate Limit) pin: connect to GND for 16Mbps, VCC for 500kbps, or leave unconnected for 250kbps.

Can the MAX13089E operate in half-duplex mode?

Yes, connecting the H/F (Half/Full-Duplex) pin to VCC selects half-duplex mode, while connecting it to GND or leaving it unselected enables full-duplex mode.

What is the purpose of the TXP and RXP pins?

These pins allow independent programming of the transmitter and receiver output phases. Connecting them to VCC inverts the respective signal polarity to correct for reversed twisted-pair wiring.
