MC1489AMEL

Drivers, Receivers, Transceivers Overview

The MC1489AMEL is a monolithic quad line receiver manufactured by onsemi, designed to interface data terminal equipment with data communications equipment in conformance with EIA-232D specifications. It operates within an ambient temperature range of 0°C to +75°C and accepts a power supply voltage of up to 10 Vdc. The device features an input signal range of ±30 Vdc and an input resistance between 3.0 kΩ and 7.0 kΩ. Electrical characteristics include a typical power supply current of 16 mA (maximum 26 mA) at 5.0 Vdc and propagation delay times ranging from 25 ns to 85 ns depending on load conditions.

Drivers, Receivers, Transceivers Feature Summary

• Built-in input threshold hysteresis for enhanced noise rejection
• External response control nodes allowing adjustable logic threshold shifting
• Capable of filtering high-frequency, high-energy noise pulses via external capacitors

Drivers, Receivers, Transceivers Applications

• Interfacing data terminal equipment with data communications equipment per EIA-232D standards
• Translating signals between MOS circuits and DTL/TTL logic systems
• Paralleling receivers to meet specific EIA-232D impedance requirements

Drivers, Receivers, Transceivers Procurement Notes

Verify the part number suffix against official manufacturer documentation to confirm package type and shipping configuration. The MEL suffix indicates SOEIAJ-14 packaging in tape and reel format. Confirm RoHS compliance status and lead-free designation if required for assembly processes. Ensure compatibility with existing PCB footprints and soldering profiles before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing interfaces requiring strict adherence to EIA-232D voltage levels and input impedance constraints. Consider the MC1489A variant specifically for its higher input turn-on threshold compared to the standard MC1489. Evaluate the need for external response control components to tailor noise filtering or threshold shifting for specific application environments.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MC1489 family of quad line receivers produced by onsemi. It serves as the companion receiver to the MC1488 quad driver, forming a complete interface system. The MC1489AMEL specifically denotes the MC1489A version packaged in SOEIAJ-14 format with tape and reel shipping options.

Drivers, Receivers, Transceivers Replacement Considerations

MC1489MEL is the non-A variant with identical packaging but different electrical thresholds. MC1489DG and MC1489ADG are pin-compatible SOIC-14 alternatives. Verify functional equivalence regarding input hysteresis and threshold voltages before substitution.
