Product Introduction

Overview

The 74LVC244ADTR2G is a high-performance, non-inverting octal buffer produced by ON Semiconductor. This device operates within a wide supply voltage range of 1.2 V to 3.6 V, making it versatile for various applications. It features 5 V tolerant inputs and outputs, allowing it to interface safely with 5 V TTL logic devices. The 74LVC244A series, to which this component belongs, is designed for low-power consumption and high-speed operation, making it suitable for memory address driving and TTL level bus-oriented transceiver applications.

Key Features

  • High-performance, non-inverting octal buffer with 3-state outputs.
  • Operates from a 1.2 V to 3.6 V supply voltage.
  • 5 V tolerant inputs and outputs, allowing safe interface with 5 V TTL logic devices.
  • High impedance TTL compatible inputs to reduce current loading on input drivers.
  • TTL compatible outputs for improved switching noise performance.
  • Output Enable (OE) input to disable outputs by placing them in a HIGH Z condition.
  • Schmitt-trigger action at all inputs for tolerance of slower input rise and fall times.
  • IOFF circuitry for partial power-down mode operation.
  • Low-power consumption and CMOS technology.
  • ESD protection: HBM (ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V) and CDM (ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V).

Applications

  • Memory address driving.
  • TTL level bus-oriented transceiver applications.
  • Mixed 3.3 V and 5 V environment applications.
  • Partial power-down applications.
  • General-purpose buffering and line driving in digital systems.
