The MC1489A from Texas Instruments is a monolithic quadruple line receiver that conforms to EIA Standard RS-232C. It is designed to interface data terminal equipment (DTE) with data communication equipment (DCE).
Key electrical characteristics include an input resistance range of 3kΩ to 7kΩ and an input signal range of ±30V. The device operates from a single 5V supply and features built-in input hysteresis for improved noise immunity. It supports a maximum data rate of 1Mbps.
The MC1489A offers response control functionality, allowing for logic threshold shifting and input noise filtering through external components connected to a dedicated control pin. This provides flexibility in adapting the receiver to different signal conditions and noise environments.
Packaged in a PDIP through-hole configuration, the MC1489A is suitable for various industrial and commercial applications requiring reliable RS-232 communication interfaces. The operating ambient temperature range is 0°C to 75°C.
