74ABT543ADB,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT543ADB,118 is an octal latched transceiver with dual enable and 3-state outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features high output drive capability, sinking up to 64 mA and sourcing up to 32 mA. Propagation delays are specified between 1.0 ns and 6.7 ns depending on the signal path and operating conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Combines 8-bit octal transceiver and D-type latch functions in a single BiCMOS device
• Provides separate controls for data flow direction and storage via independent latch and output enable inputs
• Supports live insertion and extraction with power-up 3-state functionality
• Includes robust ESD protection exceeding 2000 V (HBM) and latch-up protection exceeding 500 mA

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus interfaces requiring temporary storage
• Back-to-back register configurations for bidirectional data transfer
• Systems permitting live insertion and extraction of modules

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '118' against current Nexperia or NXP documentation to confirm package type and availability status. Confirm that the SSOP24 package variant matches the design requirements. Check for any superseded datasheets or product discontinuation notices prior to finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with integrated D-type latching is required for bidirectional data paths. Ensure the application utilizes a 5 V logic family compatible with the ABT series. Verify that the SSOP24 package dimensions fit the PCB layout constraints and thermal management needs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. It integrates the functionality of the 74ABT245 transceiver and the 74ABT373 latch into one unit. The device is designed for low static and dynamic power dissipation while maintaining high speed and strong output drive capabilities suitable for demanding digital applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT543AD and 74ABT543APW are alternative package variants of the same functional device. Verify pin compatibility and physical footprint differences before substituting.
