SN74LVC374ADBRE4

Flip Flops Overview

The SN74LVC374ADBRE4 is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 1.65 V to 3.6 V. The device provides a propagation delay of 8.1 ns at 2.7 V with a 50 pF load, supporting clock frequencies up to 100 MHz. It offers high output drive capability with ±24 mA current ratings for both high and low states. The component is housed in a 20-pin TSSOP package and supports CMOS and TTL input levels.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Edge-triggered operation synchronized on the positive transition of the clock signal.
• Three-state outputs allowing direct connection to bus-oriented systems without additional drivers.
• Wide operating voltage range supporting both 1.8 V and 3.3 V logic families.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Bus-oriented memory registers
• Timing control logic

Flip Flops Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead-free and RoHS-compliant variant required for your assembly process. Confirm the package designation matches the TSSOP-20 footprint dimensions in your PCB layout. Ensure the voltage supply aligns with the 1.65 V to 3.6 V operational limits to maintain signal integrity and prevent device damage during procurement.

Flip Flops Selection Notes

Select this component when an octal storage element with high-speed performance is required. The 8.1 ns propagation delay makes it suitable for applications demanding faster data throughput compared to standard 74-series logic. Consider the ±24 mA output drive strength for driving moderate capacitive loads directly. Verify compatibility with system voltage levels, as the LVC series bridges 1.8 V and 3.3 V domains effectively.

Flip Flops Part Context

This part belongs to the SN74LVC374A family of octal D-type flip-flops. It is functionally equivalent to other variants such as the SN74LVC374ADBR and SN74LVC374ADGVR, differing primarily in packaging or manufacturing revision codes. The device is designed for use in general-purpose digital logic applications requiring reliable data storage and transfer capabilities across various industrial and consumer electronics platforms.

Flip Flops FAQ

What is the maximum clock frequency supported by this device?

The device supports a maximum clock frequency of 100 MHz under specified test conditions.

Does the SN74LVC374ADBRE4 support 5V logic inputs?

No, the absolute maximum voltage rating for inputs is typically limited to the supply voltage plus a small margin; it is not designed for direct 5V interfacing without level shifting.
