Analog Devices / Maxim Integrated MAX22500E & MAX22501E RS-485/RS-422 Transceivers
Analog Devices MAX22500E and MAX22501E RS-485/RS-422 Transceivers are optimized for up to 100Mbps high-speed communication over long cables. The MAX22500E and MAX22501E feature integrated hot-swap protection and a fail-safe receiver. This ensures 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 to extend the distance and increase 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 Analog Devices MAX22501E operates without preemphasis and is powered from a 3V to 5.5V supply. The MAX22500E is housed in a 10-pin TDFN-EP package and the MAX22501E is housed in an 8-pin TDFN-EP package. Both transceivers operate over the -40°C to +125°C ambient temperature range.
