The Renesas RAA7881552GSU#AB0 is a single-channel RS-485 transceiver in a half-duplex configuration, delivering 1 Mbps signaling over a single differential pair. It operates from a 4.5 V to 5.5 V supply rail.
Renesas lists this part as Active, with no end-of-life notification or last-time-buy window. It is ROHS3 compliant.
No. The supply voltage range is 4.5 V to 5.5 V, so it requires a 5 V rail. It is not compatible with 3.3 V logic without external level translation on the driver and receiver pins.
The difference is the package: RAA7881552GSU#AB0 comes in an 8-MSOP (3.00 mm width), while the GSP suffix typically indicates an 8-SOIC package. Both are half-duplex RS-485 transceivers with the same electrical ratings. Confirm the footprint before substituting.
The RAA7881552GSU#AB0 is functionally similar to the industry-standard MAX485 — both are half-duplex RS-485 transceivers with 1/1 driver/receiver count. However, the MAX485 typically operates from a 5 V supply and is available in 8-DIP or 8-SOIC packages. The RAA7881552GSU#AB0 uses an 8-MSOP package, so verify pin compatibility and footprint before drop-in replacement.
