Product Introduction

Overview

The 74ABT244D,602 is an octal buffer/line driver with 3-state outputs, manufactured by Nexperia (previously part of NXP Semiconductors). This device is designed to provide high-speed buffering and line driving capabilities, making it suitable for a variety of digital logic applications. It can be used as two 4-bit buffers or one 8-bit buffer, offering flexibility in circuit design.

74ABT244D 4.5 - 5.5 TTL -32 / +64 100 8 medium -40 to +85 SO20

Key Features

  • Octal buffer/line driver with 3-state outputs: Allows for high-speed buffering and line driving.
  • BiCMOS technology: Provides high speed and output drive capabilities.
  • Output drive capability: +64 mA / -32 mA.
  • Direct interface with TTL levels: Compatible with TTL logic levels.
  • Power-up 3-State: Ensures outputs are in a high-impedance state during power-up.
  • Live insertion capability: Can be safely inserted or removed from a live system.
  • IOFF circuitry: Enables partial power-down mode operation, preventing backflow current.
  • ESD protection: HBM (ANSI/ESDA/JEDEC JS-001 class 2) exceeds 2000 V, CDM (ANSI/ESDA/JEDEC JS-002 class C3) exceeds 1000 V.
  • Latch-up protection: Exceeds 500 mA per JESD78 class II level A.

Applications

  • Digital logic circuits: Ideal for buffering and driving signals in digital logic systems.
  • Bus interfaces: Suitable for octal bus interfaces requiring high-speed and 3-state outputs.
  • Partial power-down applications: Useful in systems where partial power-down is necessary.
  • Live insertion systems: Can be used in systems where components need to be inserted or removed while the system is live.
