V62/04684-01XE

Overview

The V62/04684-01XE is a quadruple bus buffer gate featuring independent line drivers with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature performance from -40°C to 125°C. The device utilizes the AHCT logic family, ensuring TTL-voltage compatibility for inputs. It is housed in a 14-pin SOIC (D) package and provides enhanced diminishing manufacturing sources support along with controlled baseline assembly.

Feature Summary

• Features independent line drivers with 3-state outputs that are disabled when the associated output-enable input is low.
• Provides TTL-voltage compatible inputs to ensure seamless integration with standard logic families.
• Includes ESD protection exceeding 2000 V per MIL-STD-883 Method 3015.
• Ensures high-impedance state during power-up or power-down when OE is tied to GND through a pulldown resistor.

Applications

• Bus-oriented communications systems
• Clock distribution circuits
• Buffering memory address/data buses

Procurement Notes

Verify the specific ordering suffix and package type against the official Package Option Addendum to confirm the correct variant. Ensure compliance with RoHS requirements and lead finish specifications such as NIPDAU. Confirm that the intended application environment falls within the specified operating free-air temperature range of -40°C to 125°C for reliable operation.

Selection Notes

Select this component when a quadruple bus buffer with 3-state control is required for 5V logic applications. The AHCT series ensures compatibility with TTL input levels while maintaining CMOS output characteristics. Consider the SOIC package for surface-mount assembly needs. Verify that the load capacitance requirements align with the switching characteristics provided in the datasheet for the target clock speeds.

Part Context

This part belongs to the SN74AHCT126-EP enhanced product line, designed for military and defense applications. It shares functional similarities with the catalog SN74AHCT126 but offers extended qualification pedigree including HAST and electromigration testing. The EP designation indicates enhanced diminishing manufacturing sources support and product-change notification protocols.

Replacement Considerations

Direct equivalents include the SN74AHCT126QDREP for standard commercial use. For automotive applications, consider the SN74AHCT126-Q1. Military versions may utilize the SN54AHCT126. Ensure pinout and electrical characteristics match before substitution.
