Product Introduction

Overview

The 74LVC273PW/AUJ, produced by Nexperia (formerly part of NXP USA Inc.), is an octal positive-edge triggered D-type flip-flop. This device is designed to operate within a wide supply voltage range from 1.2 V to 3.6 V, making it versatile for various applications. It features clock (CP) and master reset (MR) inputs, allowing for precise control over the flip-flop's state. The outputs (Qn) assume the state of their corresponding D inputs during the LOW-to-HIGH clock transition, and a LOW on the MR input forces the outputs LOW regardless of the clock and data inputs.

Key Features

  • Positive-Edge Triggered: The device is triggered on the rising edge of the clock signal.
  • Master Reset: A LOW on the MR input forces all outputs LOW, independent of clock and data inputs.
  • Wide Supply Voltage Range: Operates from 1.2 V to 3.6 V, making it suitable for various voltage environments.
  • Overvoltage Tolerant Inputs: Inputs can tolerate voltages up to 5.5 V.
  • CMOS Low Power Consumption: Low power consumption characteristic of CMOS technology.
  • Direct Interface with TTL Levels: Compatible with TTL logic levels.
  • Schmitt-Trigger Action: Inputs have Schmitt-trigger action, making the circuit tolerant of slower input rise and fall times.
  • High Output Drive Capability: Capable of driving 50 Ω transmission lines at +85 °C.

Applications

The 74LVC273PW/AUJ is suitable for a variety of applications, including:

  • Mixed Voltage Environments: Acts as a translator between 3.3 V and 5 V systems.
  • High-Speed Logic Circuits: Supports high clock frequencies up to 230 MHz.
  • Low Power Designs: Ideal for applications requiring low power consumption.
  • Robust and Reliable Systems: Features ESD protection and wide operating temperature range.
