SN74LVCH16543ADGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH16543ADGVR is a 16-bit registered bus transceiver with 3-state outputs from the Texas Instruments Widebus family. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, facilitating level translation. The device utilizes two separate configurable power-supply rails for A and B ports. It achieves a maximum propagation delay (tpd) of 5.4 ns at 3.3 V. The component is housed in a 56-pin TVSOP package and supports surface-mount installation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports dual-configurable power-supply rails for independent A and B port operation
• Provides 5.5 V tolerant inputs for safe level shifting between different logic families
• Integrates registered output architecture to maintain data integrity during transitions

Buffers, Drivers, Receivers, Transceivers Applications

• High-density data bus architectures requiring 16-bit width
• Systems necessitating voltage translation between 1.8 V/2.5 V and 3.3 V domains
• Portable equipment utilizing low-voltage CMOS logic standards

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-56 package and tape-and-reel shipping configuration. Confirm that the design accommodates the 5.5 V input tolerance specifications. Ensure the operating environment remains within the -40°C to +85°C temperature range defined by the manufacturer. Cross-reference the datasheet revision to validate electrical characteristics against current production batches.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a registered transceiver is required for 16-bit wide buses. It is suitable for applications needing simultaneous level shifting and data latching. Consider the TVSOP-56 footprint constraints during PCB layout. Evaluate the 5.4 ns propagation delay against system timing requirements. This part is appropriate for designs using the LVCH logic family for low-power consumption.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family, designed for high-performance digital systems. It complements other LVCH series components like the SN74LVCH16373ADGVR latch. The registered transceiver format distinguishes it from non-registered variants such as the SN74LVT16543DLG4. It serves as a key interface element in complex mixed-voltage electronic assemblies.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVCH16543ADGGR as an alternative package option within the same functional family. Verify compatibility with SN74LVCH16543 variants if pinout or electrical specs differ slightly.
