SN74ALS564BNSR

Flip Flops Overview

The SN74ALS564BNSR is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides a propagation delay of 14 ns, with high-level output current of -2.6 mA and low-level output current of 24 mA. Packaged in a SOIC-20 surface-mount format, it supports TTL input levels and functions as an inverting logic circuit suitable for industrial temperature ranges starting from 0°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops within a single integrated circuit package.

Flip Flops Applications

• Data storage applications requiring parallel data retention
• Register circuits for temporary data holding in digital systems
• Shift register configurations for serial-to-parallel conversion

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for the intended manufacturing process. Confirm that the operating temperature range aligns with the system's environmental constraints before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required. The ALS series offers improved speed and power consumption compared to standard LS logic. Verify that the SOIC-20 package fits the PCB layout and that the 14 ns propagation delay meets the system timing requirements.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74ALS logic family, which utilizes Advanced Low-Power Schottky technology. The SN74ALS564 variant specifically provides non-inverting functionality, while the BNSR suffix indicates the SOIC-20 surface-mount package configuration. It serves as a core memory element in digital logic designs.

Flip Flops Replacement Considerations

SN74ALS574BNSR is a documented alternative offering identical octal D-type functionality but with non-inverting output polarity instead of inverting.
