CD74HCT533E

Latches Overview

The CD74HCT533E is an octal transparent latch manufactured by Texas Instruments, belonging to the high-speed CMOS (HCT) logic family. It features eight D-type latches with TTL-compatible inputs and push-pull outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 30 MHz. It includes dual output enable controls for managing data flow. The component is housed in a 20-pin PDIP package and is rated for operation across an extended temperature range from -55°C to +125°C.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent storage elements
• TTL-compatible input structure ensuring compatibility with standard logic families
• Dual output enable functionality allowing flexible bus interfacing and control

Latches Applications

• Parallel-to-serial conversion circuits
• Bus-oriented memory register applications
• Temporary data storage in digital systems

Latches Procurement Notes

Verify the specific suffix 'E' corresponds to the PDIP-20 through-hole package variant when sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the supplier provides official datasheets matching the CD74HCT533 designation to avoid confusion with similar HCT latch variants.

Latches Selection Notes

Select this component when an octal latch with TTL-compatible inputs is required for high-speed applications. The HCT series offers speed comparable to LS TTL while maintaining CMOS power efficiency. Consider the dual output enables for complex bus architectures requiring multiple drivers or tri-state isolation.

Latches Part Context

This part belongs to the CD74HCT533 family of octal transparent latches. It shares functional similarities with other HCT logic devices but is distinct in its eight-bit parallel storage capability. The device is designed for general-purpose digital applications requiring reliable data retention and fast switching speeds within industrial temperature ranges.

Latches Replacement Considerations

Compatible substitutes include the SN74HCT533N and SN74HCT533PW. Verify pinout compatibility and electrical characteristics before substitution.
