MC74HC244AN** is a high-speed CMOS logic octal buffer/line driver manufactured by **Motorola (MOTO)**.

The MC74HC244AN is a high-speed CMOS logic octal buffer/line driver manufactured by Motorola (MOTO).

Specifications:

  • Logic Family: HC (High-Speed CMOS)
  • Number of Channels: 8 (Octal)
  • Input/Output Type: 3-State
  • Supply Voltage Range: 2V to 6V
  • High-Level Input Voltage (Min): 2V
  • Low-Level Input Voltage (Max): 0.8V
  • High-Level Output Current: -6mA
  • Low-Level Output Current: 6mA
  • Propagation Delay: 13ns (typical at 5V)
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: PDIP-20 (Plastic Dual In-Line Package)

Descriptions:

The MC74HC244AN is a non-inverting octal buffer and line driver designed for bus-oriented applications. It features 3-state outputs that can be controlled by two active-low output enable pins (OE1 and OE2), allowing the outputs to be placed in a high-impedance state when disabled.

Features:

  • High-Speed Operation: Compatible with TTL levels
  • Low Power Consumption: CMOS technology
  • 3-State Outputs: Allows bus sharing
  • Balanced Propagation Delays: Ensures signal integrity
  • Wide Operating Voltage Range: 2V to 6V
  • Pin-Compatible with 74LS244: Drop-in replacement for TTL versions

This device is commonly used in digital systems for signal buffering, bus driving, and interfacing between different logic levels.
