CD74HCT373M

Latches Overview

The CD74HCT373M is an octal transparent latch manufactured by Harris Corporation using high-speed CMOS technology. It features eight D-type latches with three-state outputs, designed for bus-oriented systems. The device operates within a supply voltage range of 4.5V to 5.5V and supports a wide operating temperature range from -55°C to 125°C. It is housed in a 20-pin SOIC package.

Latches Feature Summary

• Octal transparent latch configuration with three-state outputs
• High-speed CMOS logic construction
• Compatible with TTL logic families

Latches Applications

• Bus-oriented memory mapping
• Register files
• Working registers

Latches Procurement Notes

Verify the manufacturer origin, as this component was produced by Harris Corporation, which has undergone corporate changes. Confirm RoHS compliance status, as older Harris versions may not meet current environmental standards. Ensure the package type matches the required 20-SOIC footprint and validate the operating temperature range specifications against system requirements.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for data storage in bus systems. Consider the HCT series compatibility for direct interfacing with TTL inputs. Evaluate the propagation delay characteristics if timing constraints are critical for the specific application design.

Latches Part Context

This part belongs to the CD74HCTxx3 family of octal latches. It shares functional similarities with other variants like the CD74HC373 but differs in input threshold levels to ensure TTL compatibility. The M suffix indicates the SOIC package style.

Latches Replacement Considerations

Potential substitutes include the CD74HC373M or devices from other manufacturers such as Texas Instruments or Renesas that offer equivalent octal latch functionality with three-state outputs in a 20-SOIC package.
