SN74LVTH574NS

Flip Flops Overview

The SN74LVTH574NS is an octal edge-triggered D-type flip-flop with three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features a propagation delay of 3 ns. The device provides high drive capability with output currents of -32 mA (high) and 64 mA (low). It is housed in a 20-pin SOIC package and supports surface-mount installation across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides high-drive three-state outputs suitable for direct bus driving
• Features fast switching speed with low propagation delay
• Compatible with TTL input voltage levels

Flip Flops Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Flip Flops Procurement Notes

Verify the specific suffix 'N' indicates the PDIP package variant rather than the 'NSR' or 'NS' SOIC versions listed in some databases. Confirm RoHS compliance status through official TI documentation. Ensure the operating voltage requirements align with the 2.7 V to 3.6 V specification before integration into the design.

Flip Flops Selection Notes

Select this component when high current drive capability is required for bus applications. The LVTH series offers faster performance compared to standard LVT devices. Verify that the 3.6 V maximum supply voltage matches the system power rails. Consider the PDIP package constraints if PCB space allows for through-hole mounting.

Flip Flops Part Context

This part belongs to the SN74LVTH574 family of octal D-type flip-flops. It shares functional similarities with the SN74AHCT574 and SN74HCT574 but operates at lower voltages. The LVTH series is designed for low-voltage applications requiring high drive strength and fast switching speeds.

Flip Flops Replacement Considerations

SN74LVTH574PW: TSSOP-20 package variant with identical electrical characteristics. SN74LVTH574DR: SOIC-20 package variant with identical electrical characteristics.
