RAA7881732GSU#AB0
Overview
The RAA7881732GSU#AB0 is a low-power, full-duplex RS-485/RS-422 transceiver designed for 3V to 3.6V operation. It supports data rates up to 500kbps and includes a 12uA low-power shutdown mode to extend battery life in remote applications. This transceiver is housed in a compact 10-pin MSOP package, making it suitable for space-constrained industrial and building automation designs.
Why Choose This Part
This device offers a high-performance balance of 500kbps throughput and a very low 0.8mA maximum operating current. The 15mV receiver hysteresis improves noise immunity, while the 10-pin MSOP package provides a significantly smaller footprint than standard 14-pin SOIC alternatives.
Applications
Key Specifications
Getting Started
When designing with this transceiver, ensure the full-duplex wiring (separate RX and TX pairs) is correctly terminated with 120-ohm resistors at the end of the cable run. Evaluate the 12uA shutdown mode by toggling the enable pins to minimize power draw during idle periods. Standard RS-485 protection circuits, such as TVS diodes, should be placed near the MSOP pins for IEC-61000 level transients.
