MC74HC533AFR2

Latches Overview

The MC74HC533AFR2 is a D-type transparent latch manufactured by onsemi, featuring a single channel with an 8-bit output configuration. It utilizes tri-state outputs for bus-oriented applications and operates within a supply voltage range of 2.0 V to 6.0 V. The device is housed in a 20-SOIC package and supports surface-mount installation. It exhibits low input current of 1.0 μA and high noise immunity characteristic of CMOS devices. The component complies with JEDEC standards and offers ESD protection exceeding 2000 V via HBM.

Latches Feature Summary

• Provides eight-bit data storage with transparent latch functionality
• Features tri-state outputs suitable for bus-driven systems
• Ensures high noise immunity and low input current typical of CMOS technology

Latches Applications

• Bus-oriented memory mapping
• Register operations in digital logic circuits
• Data storage for temporary holding in processing systems

Latches Procurement Notes

Verify the specific suffix 'FR2' corresponds to the required tape and reel packaging quantity when ordering. Confirm that the SOIC-20 package dimensions align with your PCB footprint requirements. Ensure the operating voltage environment remains within the specified 2.0 V to 6.0 V range to maintain signal integrity and prevent device damage during operation.

Latches Selection Notes

Select this component when an 8-bit latching solution with tri-state control is required for bus applications. The HC series ensures compatibility with standard CMOS outputs and interfaces directly with NMOS and TTL loads. Consider the 20-SOIC package size for space-constrained designs requiring surface-mount technology.

Latches Part Context

This part belongs to the 74HC logic family, known for high-speed CMOS operation compatible with TTL inputs. The 533 variant specifically provides octal D-type latches with tri-state outputs. It serves as a fundamental building block for sequential logic circuits requiring data retention and controlled output enablement in microprocessor-based systems.

Latches Replacement Considerations

Check for direct pin-compatible alternatives such as the MC74HC533ADJR2 or generic 74HC533 variants from other manufacturers. Verify that any substitute maintains the same tri-state output capability and voltage range specifications.
