SN74AC564DWRE4

Flip Flops Overview

The SN74AC564DWRE4 is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports a propagation delay of 14 ns. It provides high-level output current of -24 mA and low-level output current of 24 mA. The component functions at temperatures between -40°C and +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data storage
• Three-state outputs allowing direct connection to bus structures without external drivers
• CMOS input structure ensuring compatibility with standard logic families while maintaining low static power consumption

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching of digital data buses
• High-speed register applications requiring wide data paths

Flip Flops Procurement Notes

Verify the specific suffix 'E4' indicates environmental compliance and packaging format distinct from non-E4 variants. Confirm the SOIC-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets system requirements. Cross-reference the datasheet revision date to confirm parameter validity. Validate that the three-state control logic aligns with the system design.

Flip Flops Selection Notes

Select this component when an octal buffer or register with three-state capability is required. The AC series offers faster switching speeds compared to standard 74LS devices. The wide voltage range allows operation in systems utilizing 3.3 V or 5 V supplies. Consider the 20-pin SOIC package for surface-mount assembly constraints.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AC564 family of octal D-type flip-flops. It is functionally similar to the SN74AC564DWR but may differ in packaging or environmental specifications due to the E4 suffix. It serves as a high-performance alternative to older logic families, offering improved speed and lower power consumption.

Flip Flops Replacement Considerations

SN74AC564DWR is a functional equivalent within the same family. Verify if the E4 suffix denotes a specific tape-and-reel quantity or RoHS status change. Check pinout compatibility before substitution.
