74ACT373SC

Latches Overview

The onsemi 74ACT373SC is an octal transparent latch with 3-STATE outputs housed in a 20-Lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of 4.5V to 5.5V and supports temperatures from -40°C to +85°C. The device features TTL-compatible inputs, reduced ICC and IOZ currents, and outputs capable of sourcing or sinking 24 mA. Propagation delays are specified at 10 ns maximum for the ACT series under standard conditions.

Latches Feature Summary

• Contains eight D-type latches with 3-STATE outputs suitable for bus-oriented system applications
• Features TTL-compatible inputs for direct interfacing with TTL logic systems
• Outputs provide high drive capability by sourcing and sinking 24 mA

Latches Applications

• Bus-oriented system data storage
• Register applications requiring transparent latch functionality
• Bus interfacing utilizing 3-STATE output control

Latches Procurement Notes

Verify the specific ordering suffix 'SC' corresponds to the 20-Lead SOIC JEDEC MS-013 package when sourcing. Confirm that the component meets the required operating temperature range of -40°C to +85°C for your application environment. Ensure compatibility with the 4.5V to 5.5V supply voltage specifications before integration into the design.

Latches Selection Notes

Select this component for designs requiring octal data latching with tri-state bus isolation. The ACT series provides faster switching speeds compared to AC variants while maintaining TTL input thresholds. Consider the 20-lead SOIC footprint for surface-mount assembly requirements. Verify that the 24 mA output current capability aligns with the load requirements of the connected bus lines.

Latches Part Context

This part belongs to the 74AC/ACT373 family of octal transparent latches originally documented by Fairchild Semiconductor. The SC suffix specifically denotes the 20-Lead Small Outline Integrated Circuit package type. This family is designed for high-speed digital applications where data transparency and bus holding capabilities are essential for system architecture.

Latches Replacement Considerations

Direct substitutes include MC74ACT373DTR2G and SN74ACT373PW. Verify pinout compatibility and package dimensions when transitioning between manufacturers. Ensure electrical characteristics such as propagation delay and output drive strength remain within acceptable limits for the target circuit.
