ON Semiconductor MC74AC245DWR2

The ON Semiconductor MC74AC245DWR2 is a high-performance, octal bidirectional transceiver designed for asynchronous communication between data buses. This integrated circuit is part of ON Semiconductor's AC series, which is renowned for its robustness and high-speed operation. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction control (DIR) input.

The MC74AC245DWR2 features an output enable (OE) input that, when high, disables both A and B ports by placing them in a high impedance state. This functionality is essential for preventing data contention on the bus lines. The transceiver is designed with advanced CMOS technology to provide low quiescent power consumption, yet is capable of driving large capacitive loads with excellent signal quality.

Key specifications of the MC74AC245DWR2 include:

• Logic Type: Transceiver, Bidirectional
