Maxim's new transceivers available now at Mouser

March 2, 2018 – Mouser Electronics, Inc. is now stocking the MAX22500E and MAX22501E RS-485/RS-422 transceivers from Maxim Integrated. Offering up to twice the data rates over longer distances compared to similar devices, the MAX22500E and MAX22501E transceivers deliver increased accuracy for demanding motion control systems, encoder interfaces, and other industrial controls.

The Maxim MAX22500E and MAX22501E half-duplex transceivers, available from Mouser Electronics, provide flexible performance with ±15 V HBM electrostatic discharge (ESD) protection to suit a variety of applications. The devices offer a large receiver hysteresis of 250 mV, which provides excellent electrical fast transient (EFT) robustness. The transceivers feature integrated hot-swap protection and a fail-safe receiver to ensure a logic-high on the receiver output when input signals are shorted or open for longer than 10 μs.

The transceivers are optimized for 100 Mbps high-speed communication over 50 m (or 50 Mbps over 100 m) in an operating temperature range of minus 40 to 125 degrees Celsius. Both transceivers feature a supply range of 3V to 5.5V as well as high receiver sensitivity and wide receiver bandwidth. Additionally, the MAX22500E transceiver includes a low-voltage logic supply down to 1.6V.

The MAX22500E transceiver features integrated pre-emphasis circuitry to allow engineers to extend cable length by up to 50 percent and increase the data rate of reliable communication. The pre-emphasis feature also enables increased encoder resolution and reduced latency. In addition, by improving the signal integrity and robustness, system designers can achieve the same level of performance with lower-cost cables, thereby reducing overall system costs.

The transceivers are supported by the fully assembled and tested Maxim MAX22500E and MAX22501E evaluation kits, which can be used for standalone evaluation or connected to an RS-485/RS-422 network for in-system evaluation.
