74LVC374ATTR

Overview

The STMicroelectronics 74LVC374ATTR is an octal D-type flip-flop with tri-state outputs, designed for high-speed digital applications. It operates within a supply voltage range of 1.65V to 3.6V and features low quiescent current of 10 µA. The device provides positive-edge triggering and non-inverted outputs, with a maximum propagation delay of 8.2ns at 3.3V with 50pF load. It is housed in a 20-TSSOP package and supports an operating temperature range from -55°C to 125°C.

Feature Summary

• Octal D-type flip-flop architecture with single element configuration
• Tri-state, non-inverted output capability for bus-oriented systems
• Positive-edge clock triggering mechanism for data latching
• Low input capacitance of 4 pF for reduced signal loading

Applications

• Bus-oriented memory register implementations
• High-performance timing control circuits
• Parallel-to-serial data conversion modules
• General-purpose storage elements in digital logic systems

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package integrity and lead-free compliance with RoHS3 standards. Check for moisture sensitivity level 1 handling requirements during storage and assembly processes.

Selection Notes

Select this component for designs requiring wide voltage operation between 1.65V and 3.6V. Consider the 20-TSSOP package for surface-mount applications needing eight parallel data lines. Evaluate thermal performance within the -55°C to 125°C range for industrial environments.

Part Context

Part of the 74LVC series, offering CMOS compatibility with TTL-level inputs. Designed for low-power applications while maintaining high switching speeds. The ATTR suffix indicates specific tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Direct substitutes include SN74LVC374ADW (Texas Instruments) and 74LVC374AD,118 (Nexperia). Verify pinout compatibility and electrical specifications before substitution.
