74ACT563SC

Latches Overview

The onsemi 74ACT563SC is an octal latch with 3-STATE outputs manufactured using FACT CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features TTL-compatible inputs, inverted outputs, and outputs capable of sourcing or sinking 24mA. It is housed in a 20-Lead Small Outline Integrated Circuit (SOIC) package.

Latches Feature Summary

• Octal D-type latches with 3-STATE complementary outputs
• Functionally identical to ACT573 but with inverted outputs
• TTL-compatible inputs for easy microprocessor interface

Latches Applications

• Input port for microprocessors
• Output port for microprocessors
• General-purpose data storage applications

Latches Procurement Notes

Verify the specific manufacturer origin, as the datasheet indicates Fairchild Semiconductor history now part of onsemi. Confirm the package type matches the required 20-Lead SOIC form factor. Ensure the application environment stays within the specified voltage and temperature limits to maintain performance.

Latches Selection Notes

Select this component when inverted octal latching functionality is required alongside 3-STATE bus driving capabilities. It serves as a direct functional alternative to the non-inverted ACT573 variant. Consider the FACT technology benefits regarding power reduction and speed for high-performance digital logic designs.

Latches Part Context

This component belongs to the 74ACT family of high-speed CMOS logic devices. It provides octal latching functionality specifically designed for buffered common Latch Enable and Output Enable inputs. The device utilizes FACT technology to reduce power consumption while maintaining high-speed operation suitable for complex digital systems.

Latches Replacement Considerations

The 74ACT573SC is functionally identical except for non-inverted outputs. Verify output polarity requirements before substitution.
