74ACQ373PC

Latches Overview

The onsemi 74ACQ373PC is an octal transparent latch with 3-STATE outputs housed in a 20-Lead Plastic Dual-In-Line Package (PDIP). It utilizes Quiet Series technology to ensure quiet output switching and improved dynamic threshold performance. The device operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 11.0ns at 3.3V and 7.5ns at 5.0V, with outputs capable of sourcing and sinking 24mA.

Latches Feature Summary

• Incorporates Fairchild Quiet Series technology for guaranteed simultaneous switching noise levels and superior dynamic threshold performance.
• Features GTO output control and undershoot corrector mechanisms alongside a split ground bus design.
• Provides eight D-type latches with 3-STATE standard outputs suitable for bus organized system applications.

Latches Applications

• Bus organized system applications
• Driving bus lines
• Buffering memory address registers

Latches Procurement Notes

Verify the specific package configuration matches the required footprint, as this component is available in multiple variants including SOIC and SOP. Confirm that the ordering code corresponds exactly to the PDIP variant intended for your design. Ensure compatibility with existing logic families and power supply constraints before finalizing procurement decisions.

Latches Selection Notes

Select this component when low noise and high-speed data latching are critical requirements for the application. The Quiet Series technology offers faster propagation delays compared to standard AC/ACT373 devices. Consider the 24mA drive capability and wide operating voltage range when designing interfaces for various digital systems requiring robust signal integrity.

Latches Part Context

This part belongs to the 74ACQ series of octal latches manufactured by onsemi (formerly Fairchild Semiconductor). It shares functional similarities with other members of the family but is distinguished by its specific packaging and enhanced noise reduction features provided by the Quiet Series technology. The device is designed to replace older generation latches in high-performance digital circuits.
