CD74AC563E

Latches Overview

The CD74AC563E is an octal transparent latch manufactured by Harris Corporation, belonging to the 74AC logic series. It features eight D-type latches with tri-state outputs, designed for high-speed data storage and bus interfacing applications. The device operates within a supply voltage range of 1.5V to 5.5V and supports a wide operating temperature range from -55°C to 125°C. It is housed in a 20-pin PDIP package with a standard 0.300-inch (7.62mm) width.

Latches Feature Summary

• Octal configuration providing eight independent D-type transparent latches for parallel data handling
• Tri-state output capability enabling direct connection to system buses without external buffers
• Wide supply voltage operation supporting both low-power and standard logic levels

Latches Applications

• Parallel data storage in digital systems
• Bus interface circuits requiring tri-state isolation
• High-speed data buffering applications

Latches Procurement Notes

Verify manufacturer origin as Harris Corporation or acquired entities like Texas Instruments. Confirm RoHS compliance status, as older Harris parts may not meet current environmental standards. Check package integrity for the 20-DIP form factor. Ensure operating temperature ratings match specific application requirements given the wide range availability.

Latches Selection Notes

Select this component when octal latching with tri-state outputs is required. Consider the 74AC series speed characteristics against power consumption needs. Verify that the 1.5V to 5.5V supply range aligns with the target system voltage. Ensure the PDIP package fits the available PCB footprint and assembly constraints.

Latches Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices. It shares functional similarities with other octal latches but offers specific AC series performance metrics. The device is often compared with variants like the CD74AC573, differing primarily in internal circuitry or packaging options while maintaining similar logical functions.

Latches Replacement Considerations

Compatible substitutes include the CD74AC573 and CD74ACT573, which offer similar octal latch functionality. Verify pin compatibility and electrical specifications before substitution. Note that ACT variants may have different voltage thresholds compared to the AC series.
