74LVT16543ADL,518

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVT16543ADL,518 is a 3.3 V 16-bit registered transceiver with 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device supports BiCMOS high-speed operation with output drive capabilities of +64 mA/-32 mA. It includes bus-hold data inputs and IOFF circuitry for partial power-down mode.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable as two 8-bit or one 16-bit registered transceiver
• Overvoltage tolerant inputs compatible with 5 V systems
• Bus-hold data inputs eliminate external pull-up resistors
• IOFF circuitry enables partial power-down mode operation

Buffers, Drivers, Receivers, Transceivers Applications

• Universal bus interface applications
• Mixed voltage system interfacing
• High-speed data transmission lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the required design constraints, as the DL suffix indicates an SSOP56 package which was removed in recent datasheet revisions. Confirm that the specific ordering code aligns with current production status and availability through authorized Nexperia channels. Ensure compliance with JEDEC standards relevant to the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a registered transceiver with latching capability is required for 3.3 V logic systems interfacing with 5 V buses. The BiCMOS technology provides high speed and strong output drive. Consider the TSSOP56 alternative if the SSOP56 package is unavailable or unsuitable for the PCB layout requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LVT (Low-Voltage TTL) logic family from Nexperia, designed for 3.3 V operation. It serves as a registered version of standard bus transceivers, adding latch functionality to control data flow direction and storage. The device is suitable for general-purpose digital logic applications requiring robust signal integrity.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74LVT16543ADGG variant if a TSSOP56 package is preferred over the SSOP56 format. Verify functional compatibility with other 16-bit registered transceivers from different manufacturers if sourcing alternatives.
