SN74BCT2953NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74BCT2953NT is an octal bus transceiver and register manufactured by Texas Instruments. It contains two 8-bit back-to-back registers designed to manage bidirectional data transfer on logic buses. The device features 3-state outputs, allowing connection to multiple buses without interference. It operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole or surface-mount installation depending on the specific package variant.

• Bidirectional data transfer on logic buses
• System memory interfacing
• Control signal routing in embedded systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact package type (e.g., SOIC, TSSOP) against your PCB footprint requirements, as 'NT' suffixes often denote specific tape-and-reel packaging but physical dimensions vary. Confirm RoHS compliance status directly from the manufacturer's current datasheet revision, as environmental declarations can change over production lifecycles. Ensure the operating temperature range matches your system's thermal environment specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional data flow requires both buffering and temporary storage at the receiving end. The dual-register architecture allows for synchronized data capture across eight lines simultaneously. Compare propagation delay characteristics against your system clock speed to ensure timing margins are met. Verify that the 3-state control logic aligns with your bus arbitration scheme to prevent contention during simultaneous access attempts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT series, which combines BiCMOS technology for high-speed operation with TTL-compatible input levels. The BCT family offers improved performance over standard 74LS logic while maintaining pin compatibility. As an octal transceiver, it serves as a critical interface element in digital systems requiring reliable data latching and direction control across parallel data paths.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other SN74BCT2953 variants with different package suffixes (e.g., SN74BCT2953N for DIP). Cross-family replacements like SN74ACT2953 offer similar functionality with AC-speed characteristics. Verify pinout compatibility and electrical parameters before substituting to ensure system integrity.
