SN74LVTH574PWE4

Flip Flops Overview

The SN74LVTH574PWE4 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 2.7 V to 3.6 V. The device provides high drive capability with output currents of -32 mA (high) and 64 mA (low). Propagation delay is specified at 3 ns. It is housed in a TSSOP-20 surface-mount package.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops
• Three-state outputs for bus-oriented system connections
• High current drive capability suitable for direct interface with CMOS, NMOS, and TTL loads

Flip Flops Applications

• Registering and buffering data in high-speed digital systems
• Bus-oriented memory and logic implementations
• Clock domain crossing synchronization circuits

Flip Flops Procurement Notes

Verify the E4 suffix indicates lead-free construction compliant with RoHS standards. Confirm the specific package variant matches the required thermal and mechanical specifications for the target PCB layout. Ensure the operating temperature range aligns with the intended environmental conditions of the final application.

Flip Flops Selection Notes

Select this component when low-voltage operation between 2.7 V and 3.6 V is required alongside high drive strength. The LVTH series offers faster propagation than standard LVT devices. Consider the TSSOP-20 footprint constraints and thermal dissipation requirements during the design phase.

Flip Flops Part Context

This part belongs to the SN74LVTHxx family, designed for low-voltage applications requiring robust output drive. It serves as a successor to older ABT logic families, offering improved speed and power efficiency while maintaining compatibility with standard logic interfaces.

Flip Flops Replacement Considerations

SN74LVTH574PW is the non-lead-free equivalent. SN74LVTH574PWR is the reel-pack version of the same device.
