74AHCT1G126GZYL

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT1G126GZYL is a single non-inverting buffer and line driver featuring three-state outputs, housed in an XSON5 (SOT8065-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device provides overvoltage tolerant inputs up to 5.5 V, enabling its use as a translator in mixed-voltage environments. It ensures high noise immunity and low power dissipation while maintaining symmetrical output impedance and balanced propagation delays across the specified temperature range.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features three-state outputs controlled by an active-high enable input for bus management
• Includes overvoltage tolerant inputs allowing operation in mixed-voltage systems
• Provides high noise immunity with CMOS low power dissipation characteristics

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented transfers
• Clock driving and buffering
• Memory and signal switching applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the exact package variant and reel specifications. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the design accounts for the thermal derating curves provided in the datasheet for the XSON5 package under maximum operating conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required for 5 V logic systems. The AHCT series is appropriate for interfacing with TTL-compatible sources. Consider the XSON5 package for applications requiring a compact footprint with side-wettable flanks for improved solder joint visibility and reliability.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC/AHCT1G126 family of single bus buffers. The 'AHCT' designation indicates compatibility with TTL input levels while operating at standard CMOS supply voltages. The 'GZ' suffix identifies the specific XSON5 plastic thermal enhanced package with side-wettable flanks, distinguishing it from other variants like TSSOP5 or SC-74A.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the 74AHC1G126GZ for CMOS input levels or the 74AHCT1G126GW for alternative packaging. Verify that any substitute maintains the same three-state functionality and voltage tolerance specifications.
