CD74ACT533M

Latches Overview

The CD74ACT533M is an 8-bit transparent latch manufactured by Harris Corporation, housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 4.5V to 5.5V and supports a wide operating temperature range from -55°C to 125°C. The device features tri-state outputs for bus-driven applications and is part of the ACT logic family, designed for high-speed performance.

Latches Feature Summary

• Provides 8-bit data storage with transparent latch functionality
• Features tri-state outputs suitable for bus-oriented systems
• Designed for high-speed operation within the ACT logic family

Latches Applications

• Bus-oriented memory mapping
• Register applications requiring high-speed data transfer
• I/O buffering for microprocessor systems

Latches Procurement Notes

Verify component authenticity as the manufacturer is Harris Corporation and the part status is listed as obsolete. Confirm RoHS compliance status, which is non-compliant. Ensure the 20-SOIC package matches design requirements. Check for potential replacement options due to end-of-life status.

Latches Selection Notes

Select this component for designs requiring 8-bit latching with tri-state control in harsh environments. The ACT series offers speed advantages over standard HC/HCT families. Verify that the 4.5V-5.5V supply range aligns with system power rails. Consider the obsolete status when planning long-term production.

Latches Part Context

This component belongs to the 74ACT logic family, known for CMOS compatibility with TTL levels and improved switching speeds. The CD74 prefix indicates commercial temperature range variants within the broader CD series, though this specific part supports extended temperatures. It serves as a digital storage element in complex logic circuits.

Latches Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative sources or redesign may be necessary.
