74LVQ574TTR

Overview

The STMicroelectronics 74LVQ574TTR is an octal D-type transparent latch fabricated using advanced CMOS technology. It operates within a supply voltage range of 2V to 3.6V and supports a wide operating temperature from -55°C to +125°C. The device features eight D-type latches with three-state outputs, housed in a 20-SOIC package (SOIC20_300MIL). Designed for surface-mount installation, it complies with RoHS standards and has a moisture sensitivity level of 1.

Feature Summary

Octal configuration providing eight independent D-type transparent latches
Three-state output capability for bus-oriented systems
Wide operating voltage range supporting low-voltage applications
Extended industrial temperature rating for harsh environments

Applications

Bus-oriented memory mapping
I/O port expansion for microcontrollers
Register file storage in digital logic circuits
Data buffering in communication interfaces

Procurement Notes

Verify component authenticity through authorized channels due to the part's obsolete status. Confirm that the specific SOIC20_300MIL package matches design requirements. Check for RoHS compliance documentation if required by project specifications. Ensure replacement strategies are evaluated as this component may no longer be actively manufactured by the original supplier.

Selection Notes

Select this component when designing systems requiring octal data storage with transparent latch functionality. Consider the 2V to 3.6V operating range for compatibility with low-power logic families. Evaluate the -55°C to +125°C temperature range against environmental conditions. Verify pinout compatibility with existing PCB layouts before integration.

Part Context

This component belongs to the 74LVQ series, representing low-voltage quad/octal logic devices. It serves as a specialized variant within the broader 74xx574 family of octal D-type latches. The LVQ designation indicates specific electrical characteristics tailored for low-voltage operation compared to standard CMOS counterparts.
