ON Semiconductor MC74LCX244DWR2 - Octal Buffer/Line Driver

The MC74LCX244DWR2 is a high-performance, octal buffer and line driver designed to interface with 3.3V and 5V systems. Manufactured by ON Semiconductor, this integrated circuit is part of the LCX family, which is known for its low voltage operation and low power consumption. The device is specifically engineered to deliver exceptional signal integrity while driving heavy loads, making it a perfect choice for a wide range of applications in modern electronic systems.

The device features eight non-inverting buffers with 3-state outputs that can be employed as line drivers for bus-oriented applications. The 3-state control gate is a common feature that allows the outputs to be placed in a high impedance state, effectively disconnecting the drive to the bus. This is particularly useful in multiplexed bus systems where multiple drivers can share the same bus lines without interference.

The MC74LCX244DWR2 operates over a broad voltage range from 2.3V to 3.6V and is capable of sinking or sourcing up to 24mA at output voltages of 3.0V, making it highly versatile for interfacing with various logic levels. Furthermore, it possesses the ability to drive heavily loaded outputs up to 15pF with full-rated performance characteristics. This capability is essential for maintaining signal integrity in complex and high-speed digital environments.

ON Semiconductor has equipped the MC74LCX244DWR2 with additional features that enhance its performance, such as power-down high impedance inputs and outputs, which ensure that the device consumes minimal power when not actively driving a signal. Additionally, the device maintains excellent output current drive capability across the entire voltage range, which is critical for maintaining signal quality.

Packaged in a wide-body SOIC-20 package, the MC74LCX244DWR2 is designed for surface mount technology (SMT) and is fully compatible with standard industry reflow processes. It is also characterized for operation from -40°C to +85°C, making it suitable for use in environments with wide temperature ranges.

In summary, the ON Semiconductor MC74LCX244DWR2 is a reliable and high-performing octal buffer/line driver that provides a seamless interface between different voltage systems and ensures robust signal driving capabilities in a variety of electronic applications.
