SN74LVT2952DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT2952DW is an octal bus transceiver from Texas Instruments, belonging to the LVTH logic family. It features registered bidirectional data transmission with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports LVTTL input levels. Key electrical parameters include a propagation delay of 5.3 ns, a low-level output current of 64 mA, and a high-level output current of -32 mA. It functions as a non-inverting registered bus transceiver suitable for industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 tube packaging when sourcing. Confirm the LVTH series designation matches the required registered functionality, distinguishing it from standard unregistered bus transceivers. Ensure the operating voltage range aligns with the system's 3.3V power domain specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when registered data storage is required at the bus interface point. The LVTH series offers higher drive strength compared to standard LV devices. Consider the SOIC-20 package constraints for PCB layout. Verify that the 5.3 ns propagation delay meets the timing requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH2952 family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices, providing both signal buffering and data retention. The device integrates eight D-type flip-flops to latch incoming data before driving the external bus lines.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the difference between SN74LVT2952 and SN74LVTH2952?

The 'H' in SN74LVTH2952 indicates the use of Texas Instruments' High-Speed CMOS (HCT/LVTH) technology, which ensures compatibility with LVTTL input voltage levels, whereas standard LVT parts may have different input threshold characteristics.

Does the SN74LVT2952DW support bidirectional communication?

Yes, it is a bidirectional bus transceiver controlled by a direction pin that determines whether data flows from port A to port B or vice versa.
