ON Semiconductor MC74AC245DTR2 Octal Bidirectional Transceiver

The MC74AC245DTR2 is a high-performance, octal bidirectional transceiver designed by ON Semiconductor. This integrated circuit is part of the 74AC series, widely known for its exceptional speed and power efficiency. The device is engineered to enhance data transmission in both directions, from A to B or B to A, making it ideal for multiplexed data transmission systems and bus-oriented applications.

This transceiver features eight non-inverting bidirectional buffers with 3-state outputs and is designed to interface with 8-bit data buses and control bus timing signals. The 3-state outputs ensure that the device can be connected directly to a bus-structured system while allowing the bus lines to be used for other purposes when the outputs are in the high-impedance state.

The MC74AC245DTR2 operates at a voltage range of 2V to 6V, which provides a flexible power supply option, catering to various logic levels and making it compatible with TTL (Transistor-Transistor Logic) levels. This makes it suitable for interfacing with microprocessors or microcontrollers within a system.

ON Semiconductor's MC74AC245DTR2 comes in a TSSOP-20 package, which is a space-saving design that is ideal for modern, compact electronic assemblies. The package type aids in efficient PCB (Printed Circuit Board) space utilization, without compromising on performance or functionality.

Key features of the MC74AC245DTR2 include:

• BiCMOS technology that ensures low power dissipation
• High noise immunity characteristic of CMOS
• Capability to drive 24 mA at the outputs
• Non-inverting buffers with tri-state outputs
• Wide operating voltage range for increased versatility
• Low power consumption for energy-efficient designs

Applications for the MC74AC245DTR2 are diverse, ranging from data bus transceivers in computers and peripherals to signal buffering in data communication systems. Its robust design and reliability make it a preferred choice for designers looking to ensure seamless data flow in their digital applications.

ON Semiconductor's commitment to quality ensures that the MC74AC245DTR2 meets the stringent requirements of the electronics industry, providing a reliable solution for high-speed data transmission and reception.
