74ABT543AD,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT543AD,118 is an octal latched transceiver with dual enable and 3-state outputs manufactured by Nexperia. 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 separate latch enable (LEAB, LEBA) and output enable (OEAB, OEBA) inputs for independent control of data flow in either direction. Outputs are guaranteed to sink 64 mA and source 32 mA. Propagation delays range from 1.0 ns to 6.7 ns depending on the signal path and operating conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix '118' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm the manufacturer designation as Nexperia B.V., noting the transition from NXP Semiconductors standard product business. Ensure compliance with RoHS3 specifications and REACH regulations during procurement validation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with integrated D-type latching is required for high-performance BiCMOS applications. The device provides separate controls for data flow in each direction, allowing flexible system design. Consider the SO24 package dimensions and lead pitch if board space is constrained. Verify input transition rise and fall rates against system clock speeds to ensure timing compatibility.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. The 74ABT543A variant specifically integrates two sets of eight D-type latches with tri-state buffers. It serves as a combined solution for data acquisition and transmission, replacing discrete latch and buffer components in complex digital circuits.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ABT543APW and 74ABT543ADB are alternative package variants of the same functional device. Verify pinout compatibility and thermal characteristics when substituting between SO24, TSSOP24, and SSOP24 packages.
