Description

The MAX487CPA+ is a low-power, half-duplex RS-485/RS-422 transceiver designed for reliable serial communication over long distances. It operates within a voltage range of 4.75V to 5.25V and features a maximum data rate of 2.5 Mbps. The device incorporates a fail-safe feature that ensures a high output state when the inputs are left open, making it robust against noise and disconnections.
Its low quiescent current consumption (typically 120 µA) allows for energy-efficient designs, particularly in battery-powered applications. The transceiver supports multipoint communication, enabling connections between multiple devices on the same bus.
The MAX487CPA+ is packaged in an 8-pin DIP, facilitating easy integration into circuits. Additionally, it includes thermal shutdown protection and short-circuit protection, enhancing its reliability. This transceiver is widely used in industrial automation, telemetry, and other applications requiring long-distance data transmission.

Features

The MAX487CPA+ is a low-power, half-duplex RS-485 transceiver designed for reliable data communication in noisy environments. Key features include:
1. Low Power Consumption: Operates with a supply voltage range of 3.0V to 5.5V, drawing only 120µA during active mode and 1µA in shutdown mode.
2. Data Rate: Supports data rates up to 2.5 Mbps.
3. Transmission Distance: Can communicate over long distances, up to 4000 feet, ensuring robust signal integrity.
4. Temperature Range: Rated for operation from -40°C to +85°C, suitable for industrial applications.
5. Fail-Safe Design: Built-in fail-safe features ensure a known state at the receiver outputs in case of an idle bus.
6. Pin Configuration: Compatible with standard 8-pin DIP and SOIC packages.
7. High Noise Immunity: Differential signaling provides excellent noise immunity and reduces crosstalk.
Overall, the MAX487CPA+ is ideal for multipoint communication systems in industrial control, building automation, and remote sensor applications.
