MAX1481CUB+

Drivers, Receivers, Transceivers Overview

The MAX1481CUB+ is a software-selectable, half-/full-duplex RS-485/RS-422 transceiver housed in a 10-pin µMAX package. It operates on a single +5V supply with a typical quiescent current of 300µA and features a low-power shutdown mode reducing current to 0.1µA. The device includes one driver and one receiver with slew-rate limiting for error-free data transmission up to 250kbps. It supports up to 256 transceivers on the bus due to its 1/8-unit-load receiver input impedance.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable half-/full-duplex operation

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm the package type matches the 10-pin µMAX format. Ensure the operating temperature range aligns with your application requirements. Cross-reference the part number suffixes to confirm specific variants or revisions if necessary.

Drivers, Receivers, Transceivers Selection Notes

Select this component for space-constrained full-duplex RS-422 applications requiring low power consumption. The MAX1481 is functionally equivalent to industry-standard parts like the MAX491 and 75180. Consider the low-power shutdown feature for battery-operated devices where minimizing standby current is critical.

Drivers, Receivers, Transceivers Part Context

The MAX1481CUB+ belongs to the MAX1481/MAX1484/MAX1485/MAX1486 family of high-speed transceivers. These devices are designed to provide robust communication capabilities in a compact form factor, making them suitable for modern electronic systems where board space and power efficiency are paramount considerations.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1481 is functionally equivalent to the MAX491 and 75180. When replacing, ensure the substitute supports the same 10-pin µMAX package and maintains compatibility with the required RS-422/RS-485 standards.
