MC74ACT373MR2

Latches Overview

The MC74ACT373MR2 is an octal transparent latch featuring three-state outputs, manufactured by onsemi. It operates within a voltage range of 2.7V to 3.6V and utilizes a 20-lead Small Outline Package (SOP) with a width of 7.50mm. The device provides high-speed performance with propagation delays typical of 10ns at 5V loads. It includes overvoltage tolerant inputs compatible with 5V signals while operating at lower supply voltages. The latch allows data storage when the enable signal is inactive, maintaining output states independently of input changes.

Latches Feature Summary

• Octal configuration with three-state outputs for bus-oriented applications
• Transparent latch operation controlled by enable and latch signals
• Overvoltage tolerant inputs allowing compatibility with 5V systems
• High-speed CMOS technology ensuring low power consumption

Latches Applications

• Bus-oriented memory mapping
• Clock buffering and latching
• Register files in digital logic circuits
• Portable equipment requiring low voltage operation

Latches Procurement Notes

Verify the exact ordering suffix MR2 corresponds to the 20-SOP package and tape-and-reel quantity specified in official onsemi documentation. Confirm RoHS compliance status and lead-free finish details through current datasheets. Ensure the manufacturer part number matches the requested specifications before finalizing procurement orders to avoid compatibility issues.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for low-voltage digital designs. Consider the 2.7V to 3.6V operating range and overvoltage tolerant inputs for interfacing with 5V logic. Evaluate package constraints for the 20-SOP form factor and verify speed requirements against typical propagation delay specifications provided in the electrical characteristics table.

Latches Part Context

This part belongs to the 74ACT series of high-speed CMOS logic devices from onsemi. The ACT series combines the speed of advanced CMOS technology with standard TTL-compatible voltage levels. The MC74ACT373 specifically addresses applications requiring data storage and bus isolation in portable and battery-powered systems where power efficiency is critical.

Latches Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers such as NXP or Texas Instruments that match the 74ACT373 specification. Verify pinout compatibility and electrical parameters including voltage ranges and drive capabilities. Ensure the replacement offers the same 20-SOP package option if board space is constrained.
