IDT74LVC861AEPG

Overview

The IDT74LVC861AEPG is a high-speed CMOS octal buffer and line driver manufactured by Integrated Device Technology. It operates with a supply voltage range of 2.7V to 3.6V, ensuring compatibility with standard LVC logic families. The device features eight independent buffers, providing robust signal integrity for digital applications. It is housed in a 44-pin TSSOP package, designed for surface-mount assembly. Key electrical characteristics include low input capacitance and controlled output drive strength, optimizing performance in high-frequency data transmission environments while maintaining low power consumption.

Feature Summary

• Provides eight independent buffer channels for signal conditioning
• Operates within the standard 2.7V to 3.6V LVC supply range
• Designed for high-speed digital signal transmission with low skew

Applications

• High-speed data bus buffering
• Clock distribution networks
• Portable electronic devices requiring low voltage operation

Procurement Notes

Verify the exact suffix 'PG' corresponds to the 44-pin TSSOP package configuration. Confirm that the manufacturer designation matches Integrated Device Technology or its current successor entity. Ensure the component meets RoHS compliance standards if required for your specific manufacturing process. Cross-reference the date code and lot number against your supplier's quality documentation to guarantee authenticity and traceability before final procurement.

Selection Notes

Select this component when an octal buffer is required for 3.3V logic systems. It is suitable for designs needing high fan-out capabilities without significant signal degradation. Consider the TSSOP package constraints regarding thermal dissipation and board space. Verify that the operating voltage range aligns with the rest of the system's power rails to ensure proper logic level interfacing and noise margin stability.

Part Context

This part belongs to the 74LVC family of high-speed CMOS logic devices. It serves as a buffer solution within the broader portfolio of interface and timing products offered by IDT. The LVC series is characterized by its ability to operate at lower voltages compared to older LVCMOS standards, making it ideal for modern portable electronics. This specific model provides the octal configuration necessary for parallel data path management.

Replacement Considerations

Check for direct pin-compatible alternatives from IDT or other major logic manufacturers such as NXP or Texas Instruments. Ensure any substitute maintains the same 44-pin TSSOP footprint and 2.7V-3.6V operating range. Verify that the replacement part offers equivalent propagation delay and drive current specifications to maintain system timing integrity.
