SN74LVC161284DLG4

Specialty Logic Overview

The SN74LVC161284DLG4 is a 16-bit FET bus switch and translation transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 3.6V and supports IEEE STD 1284 protocols. The device features open-drain outputs and is housed in a 48-SSOP package with surface-mount installation. It functions as a specialized interface IC designed for high-speed data transmission applications requiring level shifting and bus switching capabilities.

Specialty Logic Feature Summary

• Supports IEEE STD 1284 protocol standards for parallel port communication
• Integrates 16-bit FET bus switching functionality for signal routing
• Provides translation transceiver capabilities between different logic voltage domains
• Features open-drain output configuration for flexible interfacing

Specialty Logic Applications

• IEEE 1284 compliant parallel port interfaces
• High-speed data bus switching systems
• Voltage level translation between 3.3V logic domains
• Specialized interface circuits requiring bidirectional data transfer

Specialty Logic Procurement Notes

Verify the specific suffix 'G4' against current manufacturer documentation to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the ordering part number matches the exact package variant required, as minor suffix changes may indicate differences in tape-and-reel specifications or environmental certifications rather than functional alterations. Cross-reference the datasheet revision date to ensure compatibility with current design constraints.

Specialty Logic Selection Notes

Select this component when designing systems that require simultaneous 16-bit bus switching and voltage translation within a single integrated circuit. It is suitable for applications needing low on-resistance FET switches combined with active drive capabilities. Consider the 48-SSOP package dimensions during PCB layout planning to ensure adequate spacing for thermal management and signal integrity in high-density designs.

Specialty Logic Part Context

This device belongs to the SN74LVC161284 family of specialized interface ICs from Texas Instruments. It complements other logic families by providing dedicated solutions for complex parallel data paths. The LVC series indicates operation at lower voltages compared to older HC or HCT counterparts, making it appropriate for modern low-power digital systems requiring robust signal integrity across mixed-voltage environments.

Specialty Logic Replacement Considerations

The SN74LVC161284DLR serves as a direct pin-compatible alternative within the same product family. Verify that the non-G4 suffix version meets all environmental and packaging requirements for the specific application before substitution.
