Description and Introduction

Octal TRI-STATEE Buffers/Line Drivers/Line Receivers The 54LS244DMQB is a part number for a specific integrated circuit (IC) manufactured by National Semiconductor (NS). It is a part of the 54LS series, which is a family of low-power Schottky (LS) TTL logic devices. The 54LS244DMQB is an octal buffer and line driver with 3-state outputs. It is designed to provide high-speed, low-power operation and is typically used in applications requiring buffering and driving of data lines.

Key specifications of the 54LS244DMQB include:

- **Logic Family:** 54LS (Low-Power Schottky TTL)
- **Function:** Octal Buffer/Line Driver with 3-State Outputs
- **Number of Channels:** 8
- **Output Type:** 3-State
- **Operating Voltage:** 4.5V to 5.5V
- **Operating Temperature Range:** -55°C to +125°C (Military grade)
- **Package Type:** Ceramic Dual In-Line Package (DIP)
- **Pin Count:** 20
- **Propagation Delay:** Typically 9.5 ns (max) at 5V
- **Output Current:** High-Level Output Current: -15 mA, Low-Level Output Current: 24 mA
- **Input Current:** High-Level Input Current: 20 µA, Low-Level Input Current: -0.36 mA

The 54LS244DMQB is designed for use in harsh environments, making it suitable for military and aerospace applications. It is characterized by its high noise immunity and robust performance under extreme conditions.
