ON Semiconductor MC74AC245DTR2G Octal Bidirectional Transceiver

The MC74AC245DTR2G from ON Semiconductor is a high-performance, octal bidirectional transceiver designed for asynchronous communication between data buses. This integrated circuit (IC) allows data flow in either direction, making it a versatile component for a wide range of digital applications, including computing, data communication, and industrial systems where bidirectional data transfer is necessary.

Constructed with advanced CMOS technology, the MC74AC245DTR2G offers optimal speed-power performance. The device features eight non-inverting bidirectional buffers with 3-state outputs and can operate as either a transmitter or a receiver. When the output-enable (OE) input is high, the device's outputs are in a high-impedance state, which effectively isolates the buses.

Key specifications of the MC74AC245DTR2G include:

• Logic Type: Octal Bidirectional Transceiver
• Number of Bits per Element: 8
• Mounting Type: Surface Mount
• Package / Case: TSSOP-20
• Operating Temperature Range: -55°C to +125°C
• Supply Voltage: 2V to 6V
• Logic Level - High: 2.1V
• Logic Level - Low: 0.9V

With its bidirectional interface capability, the MC74AC245DTR2G allows for multi-mode operation, which is essential for data exchange in modern electronic systems. The transceiver's bus-hold circuitry is designed to retain the last active state during a power down or floating input condition, enhancing the reliability of the system it's integrated into.

The device is available in a TSSOP-20 package, ensuring a compact footprint on printed circuit boards (PCBs). This small form factor, combined with its low-power consumption and high noise immunity, makes the MC74AC245DTR2G an excellent choice for space-constrained applications that require robust data transmission capabilities.

Whether you're designing a complex data processing unit or a simple communication interface, the ON Semiconductor MC74AC245DTR2G offers a high-quality, reliable solution for your bidirectional data bus needs.
