SN74LVT16646DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT16646DL is a 16-bit bus transceiver and register designed for low-voltage 3.3-V VCC operation. It features 3-state outputs and operates within a supply voltage range of 2.7 V to 3.6 V. The device supports bidirectional data transfer with TTL-compatible inputs and CMOS outputs. It functions as a registered transceiver, clocking data from the A or B bus into internal registers. The component is housed in a 56-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix (e.g., DL vs DLR) against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the design accommodates the 2.7-V to 3.6-V supply voltage range. Confirm input compatibility with the driving logic family, noting the TTL input level specification. Check for any recent lifecycle status updates or obsolescence notices directly from Texas Instruments before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver is required for 3.3-V logic systems. It is suitable for designs needing bidirectional data flow with storage capabilities. Compare pinout and electrical characteristics against similar LVT or ABT series devices if alternative sourcing is necessary. Ensure the SSOP-56 package fits the PCB layout constraints. Verify that the propagation delay and drive current meet the system timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74LVT logic family, which provides low-voltage translation and buffering solutions. The 16646 variant specifically combines bus transceiver functionality with 16-bit register storage. It is distinct from non-registered counterparts like the 74LVT16245 by including internal latching mechanisms for data synchronization.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVT16646DR is a reel-packaged equivalent of the same logical device. Other 16-bit LVT registered transceivers may serve as functional alternatives if pinouts and electrical specs align.
