SN74AC564PW

Flip Flops Overview

The SN74AC564PW is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight independent circuits with inverting outputs and three-state capability, housed in a TSSOP-20 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 drive currents of ±24 mA for both high and low states. The component functions reliably across an extended temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs allowing direct bus-driven connections without external buffers
• Inverting logic polarity for complementary signal generation
• CMOS input structure ensuring compatibility with standard digital logic interfaces

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register banks for temporary data storage in microprocessor systems
• Shift register implementations for serial data transmission
• Bus interface buffering for memory address latching

Flip Flops Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 surface-mount package variant rather than other packaging options like SOIC or DIP. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management requirements align with the specified operating temperature range during final design validation.

Flip Flops Selection Notes

Select this component when an octal latch with three-state output control is required for space-constrained designs. The TSSOP-20 package offers a compact footprint suitable for high-density PCB layouts. Consider the 2V to 6V operating range for flexibility in varying supply voltage environments compared to fixed-voltage logic families.

Flip Flops Part Context

This part belongs to the SN74AC series of advanced CMOS logic devices, designed for high-speed applications. It serves as a memory element within the broader family of Texas Instruments flip-flops, offering improved performance over standard 74LS counterparts while maintaining pin-out compatibility with legacy systems for easier migration.

Flip Flops Replacement Considerations
