ON Semiconductor MC74ACT640DWG Product Overview

The MC74ACT640DWG is a high-performance, octal transceiver manufactured by ON Semiconductor, featuring non-inverting 3-state outputs. Designed to be used in bidirectional communication between data buses, this integrated circuit ensures a seamless transfer of data with its advanced CMOS technology. The device allows for the direct interfacing with TTL levels and can operate effectively over a broad voltage range.

Key Features

• Logic Type: Octal Transceiver
• Logic Family: ACT
• Number of Channels: 8
• Direction: Bidirectional
• Voltage - Supply: 4.5V to 5.5V
• Operating Temperature: -40°C to 85°C
• Mounting Type: Surface Mount
• Package / Case: 20-SOIC W

With its bidirectional interface capability, the MC74ACT640DWG can transmit data from bus A to bus B and vice versa, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can be used to place the eight outputs in either a normal logic state or the high-impedance state, thereby allowing for the outputs to be tied together without the risk of conflict.

The device is built to ensure low power consumption while maintaining a high speed of operation. The MC74ACT640DWG also offers bus hold features which prevent floating inputs and ensure stable operation without the need for pull-up or pull-down resistors.

ON Semiconductor's commitment to quality ensures that the MC74ACT640DWG is designed for optimal reliability and performance. This transceiver is commonly used in applications such as data bus transceiving, signal gating, and in systems that require high-speed, bidirectional communication lines.

The MC74ACT640DWG is supplied in a 20-SOIC W package, which is suitable for automated pick-and-place equipment, and is available in tape and reel packaging for efficient assembly during the manufacturing process.

Overall, the MC74ACT640DWG from ON Semiconductor is a versatile and reliable solution for designers looking to facilitate robust data communication in their digital systems.
