SN74AC564DWRG4

Flip Flops Overview

The SN74AC564DWRG4 is an octal D-type edge-triggered flip-flop from the Texas Instruments AC logic family. It features eight independent D-type flip-flops with 3-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 drive capability with output currents of ±24 mA. The component functions at clock frequencies up to 90 MHz and operates across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Integrates eight independent D-type edge-triggered flip-flops for parallel data storage
• Provides 3-state outputs to facilitate direct bus-driven connections
• Delivers high current drive capability suitable for driving bus lines
• Operates with low static power consumption typical of CMOS technology

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching of address/data buses
• Clock domain crossing synchronization stages
• General-purpose register file implementations

Flip Flops Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the DWR package variant matches the required surface-mount footprint and pin pitch specifications for the target PCB layout. Ensure the operating voltage requirements align with the system's power rails before integration.

Flip Flops Selection Notes

Select this component when an octal latch with tri-state control is required in the AC logic family. It offers faster switching speeds compared to HC series alternatives while maintaining CMOS input compatibility. Consider the 20-pin SOIC package constraints and the need for inverted outputs, which distinguish it from non-inverting variants like the SN74AC574.

Flip Flops Part Context

This part belongs to the SN74AC564 series of octal D-type flip-flops manufactured by Texas Instruments. It is part of the broader 74AC logic family, designed for high-speed digital applications. The device serves as a fundamental building block for sequential logic circuits requiring multiple synchronized data storage elements with controlled output states.
