SN74LVC2952ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2952ADW is an octal bus transceiver and register with 3-state outputs manufactured by Texas Instruments. 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, supporting mixed-mode signal operation on all ports. The device consists of two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Data is stored on the low-to-high transition of the clock input when the clock-enable input is low. The maximum propagation delay is 8.2 ns at 3.3 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing use as translators in mixed 3.3-V/5-V system environments
• Includes Ioff circuitry to support partial-power-down mode and prevent damaging current backflow
• Features latch-up performance exceeding 250 mA per JESD 17 specification

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional data communication between two buses
• Mixed-mode signal translation in 3.3-V/5-V systems
• Partial-power-down applications requiring output disabling during power down

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the ordering suffix; the 'DW' suffix indicates a SOIC-24 package. Confirm RoHS compliance status and lead finish details via the latest TI Package Information Addendum. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring dual-directional data storage and transfer between buses. The LVC logic family ensures compatibility with low-voltage control signals while maintaining 5-V tolerant inputs. Consider the 3-state outputs for bus sharing applications. Verify that the clock enable and output enable pin configurations align with the system timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC series of logic integrated circuits from Texas Instruments. It combines the functionality of a bus transceiver with a register, providing data storage capabilities alongside signal direction control. The octal configuration allows for efficient handling of wide data buses in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVC2952ADWR (reel version) or other package variants like SN74LVC2952APWR if different packaging is required. Ensure functional equivalence regarding voltage levels and pinout compatibility before substitution.
