74LVC543APW,118

Overview

The NXP USA Inc. 74LVC543APW,118 is an octal D-type registered transceiver featuring 3-state outputs in a TSSOP24 package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports 5 V tolerant inputs/outputs for interfacing with 5 V logic. The device includes back-to-back registers for data storage and separate controls for bidirectional data flow. Propagation delay from An to Bn or Bn to An is typically 3.0 ns at 3.3 V with a 50 pF load.

Feature Summary

• Octal D-type registered transceiver with 3-state non-inverting outputs
• Back-to-back registers for temporary data storage in either direction
• Separate latch enable and output enable inputs for independent control
• High-impedance state when VCC is 0V

Applications

• Bus-oriented applications requiring bidirectional data transfer
• Interfacing between 5 V logic systems and low-voltage logic
• Temporary storage of data flow in digital circuits

Procurement Notes

Verify the specific suffix '118' against current manufacturer documentation to confirm availability and exact ordering specifications. Confirm that the TSSOP24 package matches the design requirements. Ensure compliance with RoHS standards as indicated in the product specification. Check for any recent Customer Product Change Notifications regarding this part number.

Selection Notes

Select this component for designs requiring octal bidirectional data transfer with latching capability. The 5 V tolerance allows direct interface with higher voltage logic levels. Ensure the operating temperature range meets the application's environmental needs. Verify power supply constraints align with the 1.2 V to 3.6 V operating range.

Part Context

This device belongs to the 74LVC family of integrated circuits, designed for low-voltage CMOS applications. It provides high performance and low power consumption compared to advanced CMOS compatible TTL families. The 74LVC543A variant specifically offers octal configuration with registered outputs for robust data handling in complex digital systems.

Replacement Considerations

Check for equivalent parts from other manufacturers offering similar octal registered transceiver functionality. Ensure pin compatibility and electrical characteristics match the original design requirements. Verify package dimensions if physical space is constrained.
