These alternatives offer similar functionalities, such as differential signaling for long-distance data transmission and low power consumption. Always check the specific requirements and specifications to ensure compatibility.
Features
1. Data Rate: Supports up to 5 Mbps, suitable for high-speed data transmission.
2. Supply Voltage: Operates from a single 5V power supply.
3. Low Power Consumption: Consumes minimal power with a typical supply current of 500 µA.
4. Half-Duplex Communication: Allows bi-directional data communication on a single pair of twisted wires.
5. Extended Temperature Range: Functions smoothly in industrial environments with an operating temperature range of -40°C to +85°C.
6. ESD Protection: Includes Electrostatic Discharge (ESD) protection on bus pins to enhance reliability and durability.
7. Driver and Receiver: Features a driver and a receiver, each with high input impedance, allowing for multiple nodes on the same bus.
8. Fail-Safe Receiver: Guarantees a known output state when the bus is idle, open, or shorted.
These features make the ADM485ARZ suitable for use in industrial, commercial, and telecommunications applications requiring robust and efficient serial communication.
Pinout
1. Pin 1 (RO): Receiver Output – Outputs the received data from the bus.
2. Pin 2 (RE\): Receiver Enable – Active low; enables the receiver when low.
3. Pin 3 (DE): Driver Enable – Activates the driver when high.
4. Pin 4 (DI): Driver Input – Data input for the driver section.
5. Pin 5 (GND): Ground – Common ground for both the driver and receiver.
6. Pin 6 (A): Driver Output/Receiver Input – Non-inverting terminal for the differential bus.
7. Pin 7 (B): Driver Output/Receiver Input – Inverting terminal for the differential bus.
8. Pin 8 (VCC): Positive Supply Voltage – Powers the device, typically 5V.
The ADM485ARZ allows for high-speed, low-power data transmission and is used in applications involving long-distance communication over twisted-pair cables.
