SN74LVT16646DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT16646DGGR is a 16-bit bus transceiver and register manufactured by Texas Instruments. It utilizes Advanced BiCMOS (ABT) technology for 3.3-V operation with low static power dissipation. The device supports mixed-mode signal operation, allowing 5-V input and output voltages while operating at 3.3 V. It features two independent 8-bit sections or one 16-bit section. Key electrical parameters include a supply voltage range of 2.7 V to 3.6 V, a maximum clock frequency of 150 MHz, and propagation delays ranging from 1 ns to 8.5 ns depending on the path. It operates within a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific DGGR suffix corresponds to the TSSOP-56 package with tape and reel packaging as documented in the ordering information. Confirm the device status is appropriate for your design, as some variants may be marked not recommended for new designs. Ensure the supply voltage requirements align with your system's 2.7 V to 3.6 V operational limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require 16-bit data transfer with integrated storage registers. It is suitable for applications needing 5-V tolerance on inputs while maintaining 3.3-V logic levels. Consider its ABT technology for low power consumption and high-speed performance up to 150 MHz. Verify thermal and electrical characteristics match your environmental conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Widebus family of Texas Instruments logic products. It is part of the LVT series, designed specifically for low-voltage 3.3-V applications. The DGGR variant indicates a TSSOP package with tape and reel delivery. It shares architectural similarities with other LVT bus transceivers but offers specific 16-bit configuration and register functionality.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVT16646DL or SN74LVT16646DLR if SSOP packaging is acceptable. Verify functional compatibility with other 16-bit bus transceivers in the LVT family. Ensure pinout and electrical specifications match before substituting.
