74LVCH16543APAG8

Overview

The 74LVCH16543APAG8 is a 16-bit registered bus transceiver manufactured by Renesas Electronics Corporation. It belongs to the LVCH logic series and utilizes a TSSOP-48 package. The device features true outputs with independent output enable controls for each direction, providing flexible signal management in high-density digital systems.

Feature Summary

• Provides registered data storage capability via integrated D-type flip-flops at the A ports.

Applications

• High-density data bus architectures requiring latched transmission.

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status and check for specific environmental declarations. Ensure the TSSOP-48 package matches design requirements. Validate that the LVCH series characteristics align with system voltage levels before integration.

Selection Notes

Select this component when registered bus transfer functionality is required within low-voltage CMOS designs. The LVCH series offers compatibility with standard logic families while maintaining low power consumption. Verify that the TSSOP-48 footprint fits the PCB layout constraints and thermal management needs of the target application.

Part Context

This part is part of the broader 74LVCH16543 family, which includes variants with different suffixes indicating packaging or temperature ranges. It serves as a registered interface solution, distinct from non-registered transceivers like the 74LVCH16543 without the 'A' designation if such distinctions exist in official documentation. It complements other logic ICs in complex digital signal processing chains.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LVCH family. Verify functional equivalence regarding registration and enable logic. Consider packages from other manufacturers only if electrical parameters and pinouts are identical per datasheet comparison.
