74AC373SC

Latches Overview

The onsemi 74AC373SC is an octal transparent D-type latch featuring three-state outputs, housed in a 20-lead Small Outline Integrated Circuit (SOIC) package. Designed for bus-oriented system applications, it provides eight independent latches within a single device. The component operates with a supply voltage range of 2.0V to 6.0V and supports an operating temperature range from -40°C to +85°C. It delivers output source and sink currents of 24mA each, ensuring robust drive capability for interfacing tasks.

Latches Feature Summary

• Contains eight D-type latches with three-state outputs suitable for bus-organized systems
• Outputs are controlled by Latch Enable and Output Enable inputs for data transparency or storage
• Provides high drive capability with outputs capable of sourcing and sinking 24mA

Latches Applications

• Bus-oriented system data storage
• Register applications requiring three-state control
• Interface circuits utilizing parallel data latching

Latches Procurement Notes

Verify the specific ordering suffix 'SC' corresponds to the 20-lead SOIC package configuration. Confirm that the component meets the required voltage and temperature specifications for the intended environment. Ensure compatibility with existing logic levels and bus architectures before integration into the design.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus interfacing. Consider the 2.0V to 6.0V supply range and 24mA output drive capability. Verify that the 20-lead SOIC package fits the board layout constraints and thermal requirements of the application.

Latches Part Context

This device belongs to the AC/ACT373 family of octal transparent latches with three-state outputs. Originally manufactured by Fairchild Semiconductor, the product line is now managed under the onsemi brand. The 74AC373 variant specifically supports a wide supply voltage range compared to the ACT version, which is limited to 4.5V to 5.5V.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74AC373 devices in the same SOIC package. Cross-reference pinouts and electrical characteristics to ensure compatibility with the existing circuit design.
