Pinout
The MAX3280EAUK is a low-power, 2.5V to 5.5V, RS-485/RS-422 transceiver. It is designed for half-duplex communication and features a pin count of 5. The pin functions are as follows:
1. RO (Receiver Output): This pin outputs the data received from the bus.
2. RE¯¯ (Receiver Enable): This active-low input enables or disables the receiver. When low, the receiver is active; when high, the receiver is disabled.
3. DE (Driver Enable): This active-high input enables or disables the driver. When high, the driver is active; when low, the driver is disabled.
4. DI (Driver Input): This pin takes the data input for transmission onto the bus.
5. A/B (Receiver Inputs/Driver Outputs): These differential pins serve as both the data input for the receiver and the data output for the driver, allowing for half-duplex operation over the bus.
The MAX3280EAUK is particularly suited for applications requiring low-power operation, such as battery-powered communication devices.
