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). Packaged in a 20-pin SOIC, it supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• High-speed data storage with 3 ns propagation delay for efficient bus driving
• Strong output drive capability supporting heavy capacitive loads
• Compatible with standard TTL input logic levels

Flip Flops Applications

• Buffer registers for data latching
• I/O port interface circuits
• Bidirectional bus drivers

Flip Flops Procurement Notes

Verify the package type matches the required footprint, as the NS suffix indicates a plastic small-outline package. Confirm that the operating voltage range aligns with the system's power supply rails. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure thermal management meets the specified junction temperature limits during operation.

Flip Flops Selection Notes

Select this component when low-voltage operation between 2.7 V and 3.6 V is required alongside high-speed performance. The LVTH series offers faster switching than standard LVTTL devices while maintaining TTL compatibility. Consider the high output current ratings for applications driving multiple loads or long traces on a PCB without additional buffering stages.

Flip Flops Part Context

This part belongs to the SN74LVTH574 family of octal D-type flip-flops. It shares functional similarities with other Texas Instruments logic families but is optimized for lower voltage applications compared to the 5 V AHCT or HC series. The device serves as a key building block for synchronous digital systems requiring reliable data retention and fast transition times.
