SN74LVTH574DB

Flip Flops Overview

The SN74LVTH574DBR is an octal D-type flip-flop from the Texas Instruments LVTH series, housed in a 20-pin SSOP package. It features three-state outputs and non-inverting logic with TTL-compatible inputs. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports a maximum clock frequency of 150 MHz. Key electrical parameters include a propagation delay of 3 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state outputs enable direct bus-driven connections without external buffer drivers.
• TTL-compatible input structure ensures compatibility with standard logic families.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in microprocessor systems
• I/O port buffering for peripheral interface control

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the component meets RoHS compliance requirements relevant to your manufacturing standards. Cross-reference the datasheet revision history to confirm that the technical parameters match the intended design constraints before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed data latching with a wide voltage tolerance. The LVTH series offers robust performance at 3.3 V while maintaining compatibility with lower voltage logic levels. Consider the SSOP package dimensions for PCB layout constraints and verify that the thermal characteristics align with the expected ambient operating conditions of the target application environment.

Flip Flops Part Context

This part belongs to the SN74LVTH574 family of octal edge-triggered flip-flops. It is designed for high-density memory and register applications where speed and power efficiency are critical. The LVTH technology combines the speed of ABT logic with the low power consumption of LVT logic, making it suitable for battery-powered and portable electronic devices requiring reliable data storage.

Flip Flops Replacement Considerations

Direct substitutes include the SN74LVTH574DWE4 and SN74LVTH574PWR. Verify pinout compatibility and electrical specifications before swapping components in existing designs.

Flip Flops FAQ

What is the maximum clock frequency supported by this device?

The SN74LVTH574DB supports a maximum clock frequency of 150 MHz under specified load conditions.

Does this component have inverting or non-inverting outputs?

The SN74LVTH574DB features non-inverting outputs, meaning the Q output follows the D input state upon clock activation.
