74LVTH574MTCX

Overview

The onsemi 74LVTH574MTCX is an octal D-type flip-flop featuring three-state outputs, manufactured using low-voltage CMOS technology. It operates within a supply voltage range of 2.7 V to 3.6 V and supports a maximum clock frequency of 150 MHz. The device provides high drive capability with output currents of -32 mA (high) and 64 mA (low), while maintaining a typical propagation delay of 5.3 ns. Packaged in a 20-TSSOP surface-mount format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture with non-inverting data paths
• Three-state outputs enabling direct bus-driven interfacing without external buffers
• Low-voltage CMOS construction optimized for power efficiency and signal integrity

Applications

• Parallel-to-serial data conversion circuits
• High-speed buffering and register stages in digital systems
• Clock domain crossing synchronization logic

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package markings and datasheet revisions match the specific lot code. Check for RoHS compliance documentation as manufacturing processes may have evolved prior to discontinuation. Ensure storage conditions adhere to moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this component when designing low-voltage logic interfaces requiring high drive strength and moderate speed. Compare against standard voltage alternatives if system power rails exceed 3.6 V. Consider pin-compatible successors from other manufacturers if long-term availability is critical for production runs.

Part Context

This part belongs to the 74LVTH series of low-voltage translation logic devices. It complements transparent latches like the 74LVTH573 by providing registered output functionality. The family targets applications needing interface between different voltage domains while maintaining fast switching speeds.

Replacement Considerations

SN74LVTH574PWR and SN74LVTH574PW are confirmed direct substitutes from Texas Instruments.
