74HC563FP-E

Latches Overview

The 74HC563FP-E is an octal D-type transparent latch manufactured by Renesas Electronics Corporation, part of the NXP-derived 74HC series. It features three-state outputs and inverting logic. The device operates within a supply voltage range of 2.0V to 6.0V. It provides high noise immunity and is designed for applications requiring parallel data storage with controlled output enablement.

Latches Feature Summary

• Octal configuration providing eight independent D-type transparent latches
• Three-state outputs allowing direct bus connection without external buffers
• Inverting logic function where outputs reflect the complement of input states when enabled

Latches Applications

• Parallel data storage in microprocessor systems
• Bus interface circuits requiring tri-state control
• Digital signal processing equipment

Latches Procurement Notes

Verify the manufacturer marking on the component body matches Renesas Electronics Corporation or authorized licensee markings. Confirm the package type corresponds to the specified FP (Small Outline) variant. Check date codes against current production status as this component may be subject to lifecycle changes. Ensure compatibility with existing PCB footprint dimensions.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for digital logic designs. Consider the 74HC series speed and power characteristics relative to system requirements. Verify that the inverting output polarity aligns with the circuit design needs. Ensure operating voltage levels match the system's logic family standards.

Latches Part Context

This component belongs to the widely adopted 74HC logic family, known for high-speed CMOS operation compatible with TTL inputs. The 74HC563 specifically addresses the need for parallel data retention in complex digital systems. Its transparent latch nature allows data to pass through until the latch enable signal activates, storing the state for subsequent processing stages.

Latches Replacement Considerations

Cross-reference with other manufacturers' 74HC563 equivalents such as those from Texas Instruments or ON Semiconductor. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part supports the same voltage range and package dimensions.
