RS-485/422 half-duplex transceiver for 5V industrial buses
Rated for 10 Mbps signaling, it suits point-to-point or multi-drop industrial links where noise immunity matters — the 35 mV receiver hysteresis helps reject bus chatter common in motor-drive and factory-floor environments.
What the 10 Mbps and 35 mV hysteresis mean on the bus
At 10 Mbps, the driver edge rate is fast enough for high-speed data capture and real-time control loops, but the half-duplex nature means you need to manage the driver-enable turnaround — mind the dead-time between transmit and receive to avoid contention on the bus. The 35 mV receiver hysteresis filters out low-amplitude noise that would otherwise cause false transitions on long cable runs. In a motor-drive cabinet with PWM switching nearby, that hysteresis margin buys you reliable frame sync without external filtering.
5 V supply rail — not 3.3 V compatible without level translation
Its logic inputs are referenced to that rail, so direct connection to a 3.3 V microcontroller UART will not meet the VIH threshold. A level shifter or a 5 V-tolerant UART is needed on the controller side.
