SN74ALS564BDWR

Flip Flops Overview

The SN74ALS564BDWR is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments within the ALS logic series. It features three-state outputs and accepts TTL input levels with inverting polarity. The device operates on a single supply voltage ranging from 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 is housed in a 20-SOIC surface-mount package and supports a minimum operating temperature of 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 bus connections while minimizing loading effects on system lines.
• TTL-compatible input thresholds ensure reliable signal recognition across standard digital logic families.

Flip Flops Applications

• Parallel data buffering and temporary storage in high-speed digital systems
• Interface circuits connecting microprocessors to peripheral devices via shared buses
• State retention modules in complex sequential logic control units

Flip Flops Procurement Notes

Verify the specific suffix 'BDWR' against official Texas Instruments documentation to confirm the SOIC-20 surface-mount package and reel packaging format. Ensure the component meets the required ALS logic family specifications and that the manufacturer identification matches the original source before integration into production designs.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data latching with active bus isolation capabilities. The ALS series offers a balance of speed and power consumption suitable for moderate-frequency applications. Confirm that the 14 ns propagation delay aligns with the system timing constraints and that the 20-SOIC footprint fits the available PCB layout space.
