The MC1489PG is a quad line receiver integrated circuit (IC) component that is designed specifically for RS-232 communication systems. It is an advanced version of the popular MC1488P and MC1488N devices.
Key features of the MC1489PG include:
1. Quad Line Receiver: The IC consists of four independent line receivers, allowing simultaneous reception of data from four different data lines.
2. Wide Input Voltage Range: The device has a broad input voltage range, which enables it to operate with various RS-232 voltage levels, typically between -30V and +30V.
3. High Noise Immunity: The IC incorporates Schmitt trigger inputs, providing a high degree of noise immunity. It allows the device to receive reliable data even in electrically noisy environments.
4. Data Transmission Speed: The MC1489PG is capable of handling high-speed data transmission rates, often up to 120 kbps, making it suitable for applications requiring quick data transfer.
5. Common-Mode Rejection: It features excellent common-mode rejection ratio (CMRR), which helps in rejecting common-mode noise signals, thus improving the overall noise rejection capability of the IC.
6. Wide Temperature Range: The IC is designed to operate reliably within a wide temperature range, typically ranging from -40°C to +85°C. This extended temperature tolerance makes it suitable for use in various industrial and commercial environments
