Product Details
The MAX3080 is a full-duplex
high-speed RS-485/RS-422 Transceiver containing
one driver and one receiver.
The MAX3080 features slew-rate limited
drivers that minimize EMI and reduce reflections
caused by improperly terminated cables, allowing
error-free data transmissions up to 115kbps. The MAX3080
typically draws 375µA of supply current when unloaded and
includes a low-power shutdown mode.
Features
- True Fail-Safe Receiver While Maintaining EIA/TIA-485 Compatibility
- Enhanced Slew-Rate Limiting Facilitates Error-Free Data Transmission
- 1nA Low-Current Shutdown
- Up to 256 Transceivers on the Bus
