74ABT543APW,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT543APW,118 is an octal latched transceiver with dual enable and 3-state outputs manufactured by NXP USA Inc. It utilizes high-performance BiCMOS technology to combine low static and dynamic power dissipation with high speed and high output drive capabilities. The device integrates two sets of D-type latches for temporary data storage in either direction, featuring separate latch enable and output enable inputs for independent control. It supports live insertion and extraction, includes power-up 3-state functionality, and offers robust ESD protection exceeding 2000 V (HBM) and 200 V (MM).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Combines 74ABT245 and 74ABT373 type functions in one device
• Back-to-back registers for storage
• Separate controls for data flow in each direction
• Live insertion and extraction permitted

Buffers, Drivers, Receivers, Transceivers Applications

• Temporary storage of data flowing in either direction
• Octal registered transceiver applications
• Systems requiring independent control of data transfer

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '118' against current Nexperia or NXP documentation, as standard datasheets often list 'PW' without a suffix or with different codes. Confirm package details match SOT355-1 (TSSOP24). Ensure compatibility with the transition from NXP Semiconductors to Nexperia for any legacy references.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring an octal bus transceiver with integrated latching capability. It is suitable for applications needing high output drive and low power consumption. Verify that the TSSOP24 package fits the PCB layout constraints and that the voltage levels align with the system's 4.5 V to 5.5 V operating range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT543A series, which are octal latched transceivers with dual enable and 3-state outputs. The series is designed for high-speed data transfer and storage in bidirectional bus systems. The APW variant specifically denotes the TSSOP24 plastic thin shrink small outline package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as SN74ABT543APWR from Texas Instruments or other 74ABT543A variants from different manufacturers. Ensure pinout and electrical characteristics match before substitution.
