74HC564D,652

Overview

The 74HC564D,652 is an 8-bit bus driver manufactured by NXP USA Inc. It features inverted outputs and operates within a supply voltage range of 2V to 6V. The device utilizes a 16-pin SO package (SOT109-1) and supports synchronous operation with separate clock inputs for data storage. It is designed for high-speed applications, offering low power consumption and noise immunity characteristic of the HC CMOS logic family.

Feature Summary

• Provides 8-bit bidirectional data transfer capability between buses
• Features inverted output configuration for signal inversion during transmission
• Incorporates D-type flip-flops with separate clock inputs for precise data latching

Applications

• Bidirectional bus drivers in digital systems
• Data storage interfaces requiring synchronized data transfer
• Memory interface circuits utilizing 8-bit data paths

Procurement Notes

Verify the specific ordering code 74HC564D,652 against official NXP documentation to confirm package type and electrical characteristics. Ensure compatibility with system voltage requirements and logic levels before integration. Cross-reference pinout configurations with standard SOIC-16 layouts to prevent assembly errors during PCB design and manufacturing processes.

Selection Notes

Select this component when an 8-bit bidirectional buffer with inverted outputs is required. It is suitable for designs needing synchronous data storage with separate clock control. Consider the HC series speed and power trade-offs compared to HCT or AC variants based on the specific timing constraints and voltage domains present in the target application architecture.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by NXP. The series is known for wide operating voltage ranges and compatibility with standard CMOS logic families. The 74HC564 specifically addresses the need for buffered, stored data transfer in complex digital architectures where signal integrity and synchronization are critical.

Replacement Considerations

Check for direct equivalents such as the 74HCT564 if TTL input compatibility is required instead of CMOS. Verify pin-to-pin compatibility with other manufacturers' 8-bit bus drivers like those from Texas Instruments or ON Semiconductor, ensuring logical function and electrical parameters match the original design specifications.
