MC1489 Description

Short technical summary and product information.

The Texas Instruments MC1489 is a monolithic low-power Schottky quadruple line receiver. It is designed to meet or exceed the requirements of TIA/EIA-232-F and ITU Recommendation V.28 standards, making it suitable for interfacing data-terminal equipment with data-communication equipment.

This device features four independent receivers, each with a built-in input hysteresis for improved noise immunity. The input resistance ranges from 3 kΩ to 7 kΩ, and it can handle an input signal range of ±30V. The MC1489 operates from a single 5V supply and supports data rates up to 1 Mbps.

A response-control terminal is provided for each receiver, allowing for adjustable input threshold levels. An external capacitor can be connected to provide input noise filtering. The MC1489 is available in a PDIP (N) package and operates over a temperature range of 0°C to 70°C.

This part is obsolete and no longer in production. New designs should consider an alternate product such as the TRS3237E.
