The MAX487ESA+T is an integrated circuit (IC) component that belongs to the MAX487 series of low-power transceivers. It is a key component that enables bidirectional communication on multi-point bus systems. The IC is designed to operate with a single 5V power supply, making it suitable for use in various industrial and automotive applications.
One of the key features of the MAX487ESA+T is its low power consumption. With a supply current of only 120µA, it is tailored to meet the demand for energy-efficient solutions. This characteristic ensures a longer battery life and reduced power dissipation, making it ideal for portable and battery-powered devices.
The IC incorporates a slew-rate-limited driver, which minimizes electromagnetic interference (EMI) and prevents reflections from high-impedance termination points. This feature makes it suitable for applications where data rates of up to 250kbps are required.
The MAX487ESA+T is equipped with a receiver that has fail-safe circuitry. This means that when no input signal is detected, the receiver output bus pins remain at a logic high level. It ensures that the bus remains in a known state and prevents false data from being transmitted.
Another notable feature of this IC is its high receiver input impedance, which allows multiple receivers to be connected to the bus without affecting signal integrity. Additionally, the built-in thermal shutdown protection prevents the IC from overheating during fault conditions, ensuring safe operation even in demanding environments
