Description

Create a design and simulate using EE-Sim^® tools:

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 protectionand 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.

Both transceivers operate over the -40°C to +125°C ambient temperature range.
