Flexibility for Many Different Applications
- 3V to 5.5V Supply Range
- Low 5µA (max) Shutdown Current (MAX22507E)
- Allows up to 200 Transceivers on the Bus
- Available in a 10-pin µMAX Package (MAX22507E) and 8-pin SOIC Package (MAX22508E)
- -40°C to +125°C Operating Temperature Range

The MAX22507E/MAX22508E ESD-protected RS-485/RS-422 full duplex transceivers are optimized for high-speed communication up to 50Mbps. These transceivers feature integrated hot-swap protection and a fail-safe receiver, ensuring a logic-high on the receiver output when input signals are shorted or open for longer than 10µs (typ). Additionally, a large receiver hysteresis improves noise rejection and signal integrity.

The MAX22507E/MAX22508E are designed to operate in harsh industrial environments and are optimized for robust communication in environments with high levels of electromagnetic interference (EMI).

The MAX22507E is available in a 10-pin µMAX package and the MAX22508E is available in an 8-pin SOIC package. µMAX is the Maxim-trademarked equivalent to the industry-standard MSOP package. Both transceivers operate over the -40°C to +125°C temperature range.

Product Details

The MAX22507E evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the functionality of the MAX22507E and the MAX22508E full-duplex high speed RS-485/RS-422 transceiver. The EV kit includes on-board termination for easy point-to-point evaluation. The EV kit is assembled using MAX22507E in a 10-pin TDFN package, but also provides equivalent functional evaluation for the MAX22508E, which is offered in a 8-pin SOIC package.
