SN74LVC374ADBR

Flip Flops Overview

The SN74LVC374ADBR is an octal D-type flip-flop manufactured by Texas Instruments, featuring three-state outputs and positive-edge triggering. It operates within a supply voltage range of 1.65 V to 3.6 V and supports a maximum clock frequency of 100 MHz. The device exhibits a propagation delay of 8.1 ns at 2.7 V with a 50 pF load, while reaching 7 ns at 3.3 V under identical conditions. Output drive capability provides 24 mA for both high and low states. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 20-SSOP package.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type flip-flops within a single integrated circuit
• Positive-edge triggered data capture synchronized with the rising edge of the clock signal
• Three-state outputs allowing direct connection to bus-oriented systems without external drivers
• CMOS compatible input structure ensuring compatibility with standard logic families

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register banks for buffering data in microprocessor-based systems
• Shift register implementations for sequential logic applications
• I/O port expansion on embedded controllers requiring tri-state isolation

Flip Flops Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout and electrical characteristics match project requirements. Confirm RoHS compliance status through current datasheets as specifications may evolve. Ensure the SSOP-20 package dimensions align with PCB footprint constraints. Cross-reference the component marking code with factory labels to authenticate genuine Texas Instruments products before integration into production assemblies.

Flip Flops Selection Notes

Select this component when designing systems requiring wide voltage operation between 1.65 V and 3.6 V with moderate speed performance. The 24 mA output drive strength suits direct interfacing with CMOS loads. Consider the 20-SSOP package for surface-mount assembly where space efficiency is prioritized over through-hole robustness. Evaluate thermal management needs given the specified operating temperature range limits.

Flip Flops Part Context

This part belongs to the SN74LVC374A family of octal flip-flops produced by Texas Instruments. It shares functional similarities with other variants like the SN74LVC374ANSR but differs in physical packaging. The LVC series designation indicates Low Voltage CMOS technology optimized for modern low-power digital applications. This specific model represents a standard industry solution for general-purpose data storage tasks.

Flip Flops Replacement Considerations

SN74LVC374ANSR offers identical functionality in a 20-SOIC package. SN74LVC374ARGYR provides similar features in a VQFN-20 package. Verify pin compatibility and thermal dissipation requirements when substituting these alternatives.
