Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system requirements before procurement. Cross-reference part numbers with authorized distributors to confirm authenticity and availability status.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring half-duplex communication with up to 128 nodes on the bus. Verify that the operating temperature range of 0°C to +70°C meets environmental specifications. Confirm that the 2.5Mbps data rate is sufficient for the application's bandwidth needs.

Drivers, Receivers, Transceivers Part Context

The MAX1487 belongs to the MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487 family of low-power transceivers designed for RS-485 and RS-422 communications. This family provides various options for full-duplex and half-duplex configurations with different slew-rate limitations and power consumption profiles.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same family include MAX1487CSA (SOIC package) or MAX1487EPA (Extended temperature). Verify pinout compatibility and electrical characteristics when substituting.
