ON Semiconductor MC74ACT244DTR2G - Octal Buffer/Line Driver

The MC74ACT244DTR2G is a high-performance, octal buffer and line driver designed to provide bidirectional drive for bus-oriented microprocessor and digital communication systems. Manufactured by ON Semiconductor, this integrated circuit is part of the ACT series that utilizes advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power dissipation.

Key Features

• Logic Type: Octal Buffer/Line Driver, Non-Inverting
• Number of Channels: 8
• Supply Voltage: 4.5V to 5.5V
• Operating Temperature: -40°C to +85°C
• Output Current: 24mA
• Mounting Type: Surface Mount
• Package / Case: TSSOP-20
• Logic Level - Low: 0.5V
• Logic Level - High: 1.5V

The MC74ACT244DTR2G is designed for use as input/output port for bus expansion, memory drivers, and all systems that require high current drive capability and buffering. The device features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout. The three-state controls allow independent input and output control, providing the highest flexibility for bus interfacing.

Each non-inverting buffer has a 3-state output that enables the device to be used in a bus-oriented configuration. The 3-state outputs are controlled by the output enable inputs (OE1 and OE2). A high level at the OE input can disable the device so that the buses are effectively isolated.

Applications

• Bus-oriented systems
• Memory drivers
• Data transmission systems
• Microprocessor systems

The MC74ACT244DTR2G ensures high noise immunity and the ability to drive 24mA at the outputs. This makes it particularly suitable for interfacing with high-speed logic and is compatible with most TTL families. Packaged in a slim TSSOP-20 package, it offers a reduced footprint on PCBs, which is beneficial for space-constrained applications.

ON Semiconductor's commitment to quality and reliability is evident in the MC74ACT244DTR2G, making it a preferred choice for designers looking for robust performance in their digital logic applications.
