MC26LS30DG

Drivers, Receivers, Transceivers Overview

The MC26LS30DG is a dual differential and quad single-ended line driver manufactured by onsemi in an SO-16 package. It supports EIA-422-A differential mode with data rates up to 10 Mbaud using a +5.0 V supply, or EIA-423-A single-ended mode with slew rate control using ±5.0 V supplies. Each output sources and sinks currents exceeding 50 mA, featuring short circuit protection and high impedance states. The device operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Configurable as two differential drivers compliant with EIA-422-A standards or four single-ended drivers compliant with EIA-423-A standards.
• Outputs capable of sourcing and sinking currents in excess of 50 mA with integrated short circuit current limiting.
• Individual slew rate control pins allow adjustment of output signal transition speeds to reduce crosstalk in single-ended applications.

Drivers, Receivers, Transceivers Applications

• EIA-422-A differential communication systems requiring high noise immunity and common mode rejection.
• EIA-423-A single-ended transmission lines where controlled slew rates are necessary to minimize crosstalk.
• Industrial and commercial serial data interfaces utilizing twisted pair or parallel cable topologies.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G' indicates a lead-free package configuration when sourcing components. Confirm that the SO-16 surface mount package matches the target PCB footprint requirements. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and revision status prior to integration into production designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring flexible interface standards without changing hardware. Use the differential mode for long-distance or noisy environments supporting up to 10 Mbaud. Choose the single-ended mode for shorter runs where individual output slew rate management is required to meet FCC emissions limits or reduce signal interference between adjacent traces.

Drivers, Receivers, Transceivers Part Context

This device serves as a functional replacement for legacy parts such as the AMD AM26LS30 and National Semiconductor DS3691. It maintains compatibility with standard TTL, CMOS, and MOS input logic levels while providing robust drive capabilities. The SO-16 package offers a compact solution for space-constrained board layouts requiring multiple driver channels.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed direct replacements include the AMD AM26LS30 and National Semiconductor DS3691. Verify pinout compatibility and electrical specifications against these equivalents before substitution. Ensure that any alternative component meets the same EIA-422-A and EIA-423-A compliance requirements.

Drivers, Receivers, Transceivers FAQ

How is the operating mode selected?

The Mode pin (Pin 4) determines the configuration. A logic low selects differential EIA-422-A mode, while a logic high selects single-ended EIA-423-A mode.

What is the maximum data rate in differential mode?

In differential mode, the drivers can transmit data at rates up to 10 Mbaud over a twisted pair.

How is crosstalk managed in single-ended mode?

Crosstalk is controlled using individual slew rate control pins connected to capacitors, which limit the output transition speed to comply with EIA-423-A and FCC requirements.
