SN74ALS564BN

Flip Flops Overview

The SN74ALS564BN is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments within the ALS logic series. It features inverting outputs with three-state capability, housed in a SOIC-20 package for surface mount installation. The device operates on a supply voltage ranging from 4.5 V to 5.5 V and supports TTL input levels. Key electrical characteristics include a propagation delay of 14 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It functions within a minimum operating temperature of 0°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single integrated circuit
• Three-state output architecture enabling direct bus driving and system-wide data line sharing
• Inverting logic polarity designed for specific signal path requirements in digital circuits

Flip Flops Applications

• High-speed parallel data storage and buffering in digital systems
• Interface circuits requiring isolated data latching between different voltage domains
• Register arrays in microprocessor-based control systems

Flip Flops Procurement Notes

Verify the exact suffix against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts regarding pin assignments and power distribution networks. Cross-reference the datasheet revision history to confirm current production status and any potential design changes affecting performance parameters.

Flip Flops Selection Notes

Select this component when designing systems requiring high-density octal latching with active drive capabilities. The ALS series offers a balance of speed and power consumption suitable for general-purpose logic applications. Confirm that the three-state outputs align with the target bus architecture and that the inverting polarity matches the required signal flow direction.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74ALS family, which utilizes Advanced Low-Power Schottky technology. The family provides improved switching speeds compared to standard LS logic while maintaining lower power dissipation. The SN74ALS564 specifically addresses the need for multi-bit storage elements with controlled output impedance in complex digital designs.
