SN75477DG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN75477DG4 is a dual peripheral driver manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a temperature range of 0°C to +70°C and dissipates up to 725 mW. The device features a propagation delay of 350 ns and supports CMOS and TTL input compatibility with a maximum output current of 400 mA per channel.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual peripheral driver architecture for simultaneous signal transmission
• Compatible with standard CMOS and TTL logic input levels
• High-output current capability for driving peripheral loads

Buffers, Drivers, Receivers, Transceivers Applications

• General-purpose digital peripheral interfacing
• TTL-to-peripheral level translation circuits
• CMOS logic output buffering applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free RoHS compliance and tube packaging distinct from tape-and-reel variants like 'DR'. Confirm the SOIC-8 footprint matches the target PCB design. Ensure the commercial grade (0°C to +70°C) meets environmental requirements. Cross-reference the manufacturer part number against authorized distributors to ensure authenticity and traceability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel high-current peripheral driving is required with standard logic compatibility. The SOIC-8 package offers a compact solution for space-constrained designs. Consider the 350 ns propagation delay for timing-sensitive applications. Verify that the 400 mA output current suffices for the connected peripheral load without exceeding thermal limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75477 series of dual peripheral drivers from Texas Instruments. It serves as a bridge between low-power logic families and higher-current peripheral devices. The 'G4' suffix typically denotes environmental compliance and specific manufacturing revisions within the broader product line.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN75477DRE4 is a verified alternative offering identical electrical specifications but supplied in a reel package instead of tubes. Both parts share the same core functionality and pinout.
