SN74ALS648-1NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS648-1NT is an octal bus transceiver and register from Texas Instruments' Advanced Low-power Schottky (ALS) logic family. It features eight bidirectional data paths with registered outputs, allowing for temporary data storage at the receiving end. The device supports TTL input levels and provides three-state outputs to facilitate efficient bus management in digital systems.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated registration capability stores data at the output pins upon clock activation
• Bidirectional data transfer between two buses controlled by direction signals
• Three-state outputs isolate the device when disabled to prevent bus contention

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional data buffering in microprocessor-based systems
• Temporary data storage within communication interfaces
• Bus isolation in complex digital circuit architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '1N' against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the package type matches the target PCB footprint requirements before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when both bus driving capability and data latching are required simultaneously. Compare propagation delays and power consumption against standard ALS alternatives if system timing constraints are tight or thermal management is critical.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALS series, known for improved speed and lower power dissipation compared to earlier LS logic families. The inclusion of a register distinguishes it from simple transceivers like the SN74ALS642A, adding functionality for data retention during bus transitions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ALS648ANT serves as a direct functional substitute with identical specifications. Verify that any alternative parts maintain the same PDIP-24 package dimensions and electrical tolerances for seamless integration.
