74LVT574PW,112

Overview

The 74LVT574PW,112 is an octal D-type flip-flop featuring positive edge triggering and three-state outputs. Manufactured by NXP USA Inc., it operates within a supply voltage range of 2.7 V to 3.6 V. The device is housed in a 20-TSSOP surface-mount package with a width of 4.40 mm. It supports high-level output currents of 32 mA and low-level output currents of 64 mA. The component exhibits a maximum propagation delay of 3 ns at 5 V with 50 pF load capacitance. It functions as a non-inverting logic circuit with single-ended inputs and includes one internal circuit containing eight bits per element.

Feature Summary

• Octal D-type flip-flop architecture with positive edge-triggered operation for synchronized data capture.
• Three-state outputs enable direct bus connections without additional interface hardware.
• High drive capability supporting 32 mA source and 64 mA sink currents for robust signal integrity.
