MC74HCT373ADTR2

Latches Overview

The MC74HCT373ADTR2 is an octal transparent latch from the 74HCT logic family, manufactured by onsemi. It features eight D-type latches with non-inverting outputs housed in a 20-TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 28 ns at 5 V and a static current of 4 µA. Output drive capabilities are specified as 32 mA for low-level output current and -6 mA for high-level output current.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent data storage elements
• High-speed CMOS technology compatible with TTL input levels
• Non-inverting output configuration for direct signal interfacing

Latches Applications

• Bus-organized system applications requiring data storage
• Interfacing TTL or NMOS outputs to High-Speed CMOS inputs
• Level conversion between different logic families

Latches Procurement Notes

Verify the complete part number including suffixes such as TR2G against official onsemi documentation to ensure correct packaging and RoHS compliance. Confirm that the TSSOP-20 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to ensure compatibility with your specific design constraints and environmental operating conditions.

Latches Selection Notes

Select this component when an octal latch with HCT-compatible inputs is required for 5V systems. It serves as a pin-for-pin replacement for LS373 devices while offering improved speed and lower power consumption. Ensure the application does not require tri-state outputs, as this variant provides standard non-inverting outputs rather than three-state control.

Latches Part Context

This component belongs to the 74HCT series of high-speed CMOS logic devices. It is functionally identical in pinout to the 74LS373 but utilizes CMOS technology for better performance characteristics. The device is designed for general-purpose digital logic applications where reliable data latching and TTL compatibility are necessary.

Latches Replacement Considerations

Public confirmed substitute part numbers include SN74HC374PWR from Texas Instruments.
