74HC564FPEL-E

Overview

The 74HC564FPEL-E is a hex buffer and line driver manufactured by Renesas Electronics Corporation. It belongs to the HC/UH series of CMOS logic devices, designed for high-speed digital applications. The component is housed in a PDSO14 plastic small outline package with a 1.27 mm pitch, measuring 5.50 x 10.06 mm. It contains six independent buffer circuits, each featuring a single input and an inverted output. The device supports a maximum operating temperature of 85 °C and has a load capacitance specification of 50 pF. It is lead-free and RoHS compliant.

Feature Summary

• Provides six independent buffering channels for signal integrity maintenance
• Features inverted outputs to function as both buffers and inverters
• Utilizes low-power CMOS technology compatible with standard logic families

Applications

• Digital signal buffering in microprocessor systems
• Line driving for communication interfaces
• Logic level translation between different voltage domains
• Signal distribution in complex digital circuitry

Procurement Notes

Verify that the received components match the exact part number 74HC564FPEL-E, ensuring the suffix indicates the specific tape and reel packaging format. Confirm the manufacturer is Renesas Electronics Corporation or its authorized predecessor entities. Check for physical damage to the SOP-14 leads and ensure the marking on the top surface corresponds to the official datasheet specifications. Validate compliance documentation such as RoHS status if required for your assembly process.

Selection Notes

Select this component when a design requires multiple buffered and inverted signals within a single integrated circuit. It is suitable for applications needing high noise immunity and low power consumption typical of CMOS technology. Consider the 14-pin package size constraints and the requirement for inverted outputs rather than non-inverted buffering. Ensure the system voltage range aligns with the HC series specifications and that the thermal environment remains within the 85 °C operational limit.

Part Context

This device is part of the widely used 74HC logic family, which serves as a standard for general-purpose digital logic functions. The HC series is known for compatibility with TTL inputs while offering improved speed and lower power dissipation compared to older LS series parts. As a hex buffer, it complements other logic gates like inverters and NAND gates in comprehensive digital design projects.

FAQ

Does the 74HC564FPEL-E provide non-inverted buffering?
