74ACTQ373SJ

Latches Overview

The onsemi 74ACTQ373SJ is an octal transparent latch with 3-STATE outputs, part of the Quiet Series utilizing Fairchild FACT technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device features eight D-type latches in a single package, housed in a 20-Lead Small Outline Package (SOP) with EIAJ TYPE II dimensions. Key electrical characteristics include propagation delays up to 9.0 ns at 5.0 V, output drive capabilities of ±24 mA, and guaranteed simultaneous switching noise levels.

Latches Feature Summary

• Utilizes Quiet Series technology for improved dynamic threshold performance and superior switching noise control.
• Features GTO output control and undershoot correction mechanisms alongside a split ground bus design.
• Provides guaranteed pin-to-pin skew AC performance for precise timing synchronization.
• Offers enhanced latch-up immunity compared to standard logic families.

Latches Applications

• Bus organized system applications requiring data storage and buffering.
• Driving bus lines or memory address registers via 3-STATE outputs.
• High-speed digital systems demanding reduced simultaneous switching noise.

Latches Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and material composition details prior to integration. Ensure that the specific SOP-20 package variant matches the required footprint constraints. Review absolute maximum ratings to prevent operational damage during system validation.

Latches Selection Notes

Select this component when low noise and high-speed performance are critical for bus-based architectures. The ACTQ series is suitable for 5 V logic environments requiring robust noise immunity. Consider the specific SOP-20 package dimensions for PCB layout compatibility. Evaluate the trade-off between the guaranteed skew performance and standard logic alternatives for precision timing requirements.

Latches Part Context

This device belongs to the 74ACQ/ACTQ family of octal latches, designed as an upgrade to standard 74AC/ACT373 components. It incorporates advanced FACT technology to address noise issues prevalent in high-density digital designs. The product line emphasizes reliability and signal integrity for complex system-on-chip and motherboard applications.

Latches Replacement Considerations

Direct substitutes include other 74ACTQ373 variants from different manufacturers offering identical pinouts and electrical specifications. Verify package compatibility, specifically the 20-Lead SOP form factor. Ensure that replacement parts maintain the same Quiet Series noise performance characteristics if applicable.
