Equipped with high-performance motion control capabilities to meet the needs of various applications
Evaluation available with the MAX22500E and MAX22501E evaluation kits

Mouser Electronics is now stocking the MAX22500E and MAX22501E RS-485/RS-422 transceivers from Maxim Integrated Products. These transceivers transmit data up to twice as fast and at longer distances than comparable devices, offering improved accuracy to meet the needs of motion control systems, encoder interfaces, and other industrial control applications.

Maxim's MAX22500E and MAX22501E, available from Mouser Electronics, are half-duplex transceivers with ±15V HBM electrostatic discharge (ESD) protection, making them ideal for a variety of applications. They feature a high hysteresis of 250mV for high electrical fast transient (EFT) immunity, and an integrated hot-swap protection and fail-safe receiver that ensures a logic high at the receiver output if the input signal is shorted or disconnected for more than 10μs.



Maxim's transceivers are suitable for high-speed communications at 100 Mbps (50 Mbps beyond 100 m) at distances exceeding 50 m and operate over a -40°C to +125°C temperature range. Both products feature a 3V to 5.5V supply voltage range, high receiver sensitivity, and wide receive bandwidth. The MAX22500E transceiver also offers a low logic voltage supply down to 1.6V.

The MAX22500E transceiver integrates pre-emphasis circuitry to extend cable length by up to 50% and increase data rates for reliable communications. Pre-emphasis characteristics increase encoder resolution and reduce latency. Furthermore, by improving signal integrity and robustness, system designers can achieve the same performance with lower-cost cables, reducing overall system costs.

Maxim's transceivers are supported and can be evaluated independently using Maxim's assembled and tested MAX22500E and MAX22501E evaluation kits. They can also be evaluated in-system by connecting to an RS-485/RS-422 network.
