ON Semiconductor MC74ACT245DTR2G Octal Bidirectional Transceiver

The ON Semiconductor MC74ACT245DTR2G is a high-performance, octal bidirectional transceiver designed for asynchronous communication between data buses. This integrated circuit is part of the ACT (Advanced CMOS Technology) family and is particularly suited for driving bus lines or buffer memory address registers due to its high noise immunity and low power consumption.

Key Features:

• Bus Interface Capability: The device allows for direct interfacing with the memory, microprocessor, or other digital components, providing a smooth flow of data in either direction through its bidirectional input/output ports.
• Non-Inverting Buffers: The transceiver features non-inverting buffers to maintain the integrity of the data being transferred.
• Output Drive Capability: With outputs capable of sinking 24mA, the MC74ACT245DTR2G can drive multiple components in a bus-oriented system.
• Tristate Outputs: The tristate outputs, which can be placed in a high-impedance state, enable the device to be disconnected from the bus line, thus allowing multiple devices to share the same bus.
• Operating Voltage Range: It operates at a voltage range of 4.5V to 5.5V, making it compatible with TTL levels.
• Low Power Consumption: The ACT series is known for its low static power consumption, contributing to energy-efficient designs.
• High-Speed Operation: The MC74ACT245DTR2G is characterized for operation from -55°C to 125°C, ensuring reliable performance even in extreme conditions.
