SN74AVC16646DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16646DGVR is a 16-bit registered bus transceiver from Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 1.2V to 3.6V and features 3-state outputs. The device includes registers that allow data on the A or B bus to be clocked into storage, enabling multiplexed transmission of registered or real-time data. It utilizes an SSOP-56 package and supports TTL input levels with CMOS output characteristics. Key electrical parameters include a propagation delay of 1.8ns at 3.3V and output drive currents of ±24mA. The component functions as a non-inverting logic circuit suitable for high-speed data transfer in portable systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the SSOP-56 package and tape-and-reel packaging configuration. Confirm the operating temperature range matches your system requirements, typically spanning -40°C to +85°C. Ensure input voltage levels are compatible with the specified TTL thresholds when interfacing with upstream logic sources. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require 16-bit data width with low voltage operation between 1.2V and 3.6V. It is appropriate for applications needing registered data paths to synchronize signals across different clock domains. Consider the SSOP-56 package constraints regarding board space and thermal dissipation. Evaluate the need for 3-state outputs to manage bus contention in multi-driver environments effectively.
