Description

The MAX22500E/MAX22501E half-duplex ESD-protected RS-485/RS-422 transceivers are optimized for high-speed (up to 100Mbps) communication over long cables.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).The MAX22500E features integrated preemphasis circuitry that extends the distance and increases the data rate of reliable communication by reducing inter-symbol interference(ISI) caused by long cables. The MAX22500E features a flexible logic interface down to 1.6V.The MAX22501E operates without preemphasis and is powered from a 3V to 5.5V supply.The MAX22500E is available in a 10-pin TDFN-EP package. The MAX22501E is available in a 8-pin TDFN-EP package and an 8-pin µMAX package. Both transceiversoperate over the -40°C to +125°C ambient temperature range.Also see the MAX22502E Full-Duplex RS-485/RS-422 Transceiver › Design Solution: RS-485: Overcome the Speed vs. Distance Challenge ›ApplicationsBackplane BussesEncoder InterfacesField Bus NetworksIndustrial Control SystemsMotion Control
