74LVTH574PW,118

Overview

The NXP USA Inc. 74LVTH574PW,118 is an octal D-type edge-triggered flip-flop featuring 3-state outputs, designed for low-voltage CMOS applications within the LVTH logic family. It operates on a single power supply ranging from 2.7 V to 3.6 V and utilizes a 20-pin TSSOP surface-mount package. The device provides non-inverting data paths with high drive capability, supporting output currents of -32 mA (high) and 64 mA (low). It exhibits a propagation delay of 3 ns at 3.3 V and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture with 3-state outputs
• High drive capability with 64 mA low-level and 32 mA high-level output current
• Fast switching performance with 3 ns propagation delay at 3.3 V
• Compatible with TTL input levels for direct interfacing

Applications

• Parallel-to-serial data conversion circuits
• I/O port expansion in embedded systems
• Buffering and latching digital signals in communication interfaces

Procurement Notes

Verify the exact part number suffix against manufacturer documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the supplier provides valid traceability documents. Check for any recent product change notices that may affect form, fit, or function. Validate lead times as availability fluctuates.

Selection Notes
