74ACQ533SC

Latches Overview

The onsemi 74ACQ533SC is a discontinued octal transparent latch featuring three-state outputs with inverted control. It belongs to the 74ACQ logic family, designed for high-speed digital applications requiring low power consumption and noise immunity. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 20-SOIC package. It provides robust output drive capabilities suitable for interfacing with various digital systems.

Latches Feature Summary

• Octal configuration providing eight independent transparent latch channels
• Three-state outputs allowing direct bus connection without external buffers
• Inverted latch enable control for flexible system integration
• Low power dissipation characteristics inherent to AC technology

Latches Applications

• High-speed data buffering in digital communication systems
• Temporary storage registers in microprocessor-based designs
• I/O port expansion for embedded controllers
• Data acquisition systems requiring parallel-to-serial conversion interfaces

Latches Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Verification of availability must rely on third-party distributors or surplus suppliers. Buyers should confirm the authenticity of existing stock and check for RoHS compliance documentation. Replacement strategies should prioritize pin-compatible alternatives from current production lines to ensure long-term supply chain stability.

Latches Selection Notes

Engineers selecting this part should consider its AC speed grade and 2V-6V operating range. The inverted latch enable function requires specific timing analysis during design. Due to discontinuation, alternative sourcing involves evaluating cross-references from other manufacturers. Design reviews must account for potential lead time variations associated with end-of-life components.

Latches Part Context

The 74ACQ533SC is part of onsemi's extended 74ACQ series, which combines AC speed with improved noise immunity. This specific model serves as an octal latch variant within the broader 74AC logic family. It was commonly used in industrial and commercial electronics before being phased out in favor of newer generation logic devices with enhanced performance metrics.

Latches Replacement Considerations

Direct substitutes include MC74ACQ533DR2G from onsemi. Cross-manufacturer equivalents such as CD74ACQ533M from Texas Instruments are also available as similar options.
