SN74ALS564BNS

Flip Flops Overview

The SN74ALS564BNS is an octal D-type edge-triggered flip-flop from the Texas Instruments ALS logic family, housed in a 20-pin SOIC package. It features three-state outputs and TTL-compatible inputs with inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 14 ns, a low-level output current of 24 mA, and a high-level output current of -2.6 mA. It supports surface-mount installation and functions at temperatures starting from 0°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data storage
• Three-state outputs enable direct connection to system buses without external buffers
• TTL-compatible input structure ensures compatibility with standard logic families
• Inverting polarity provides complementary output signals relative to the clocked input state

Flip Flops Applications

• Parallel data buffering in digital communication systems
• Register stages in microprocessor-based control circuits
• Bus interface isolation for bidirectional data transfer
• Timing synchronization elements in sequential logic designs

Flip Flops Procurement Notes

Verify the specific suffix 'N' against manufacturer documentation to confirm the exact package variant and temperature rating. Ensure the ordering part number matches the required pinout and electrical specifications for your design. Cross-reference the datasheet revision date to confirm compliance with current RoHS standards and material declarations before finalizing procurement.

Flip Flops Selection Notes

Select this component when an octal register with bus-compatible three-state outputs is required. The ALS series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the inverting polarity and TTL input requirements to ensure signal integrity and proper interfacing with upstream drivers in the circuit architecture.

Flip Flops Part Context

This component belongs to the SN74ALS5xx series of advanced small-scale integration logic devices. These parts are designed to replace older LS-series components while offering improved switching speeds and lower power dissipation. The octal flip-flop topology is a standard building block for creating wide data registers in complex digital systems.

Flip Flops Replacement Considerations

SN74ALS564DR: Same functional logic and package type but in a SOIC-20 reel format instead of tube.
