Procurement Notes

Verify the specific suffix against official documentation to confirm exact packaging configuration and reel specifications. Confirm RoHS compliance status through manufacturer declarations. Ensure the component matches the required operating temperature range for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring registered data latching on bidirectional buses. The LCX series offers superior speed compared to standard HC devices while maintaining low voltage operation. Verify that the system voltage aligns with the 2 V to 3.6 V operational window to ensure proper logic threshold performance.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic integrated circuits. The LCX series is engineered for high-speed applications requiring low power dissipation. It serves as a bridge between different logic families, facilitating interface solutions in modern electronic designs where voltage translation and signal buffering are critical requirements.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LCX family or other manufacturers' equivalent registered transceivers. Verify that substitute parts maintain identical electrical characteristics, particularly propagation delay and output drive strength, to ensure circuit compatibility.
