MAX22502EATC+

The MAX22502E full- duplex, ESD- protected, RS- 485/ RS- 422 transceiver is optimized for high- speed (up to 100Mbps) communication over long cables. This transceiver features larger receiver hysteresis for high noise rejection and improved signal integrity. Integrated preemphasis circuitry extends the distance, and increases the data rate, of reliable communication by reducing inter- symbol interference (ISI) caused by long cables when supplied with 5V. Integrated hot- swap protection and a fail- safe receiver ensure a logic- high on the receiver output when input signals are shorted or open for longer than 10μs (typ). The MAX22502E is available in a 12- pin TDFN- EP 3mm x 3mm package and operates over the - 40℃ to +125℃ ambient temperature range.
