ON Semiconductor MC74LCX244DTEL - Low-Voltage CMOS Octal Buffer

The ON Semiconductor MC74LCX244DTEL is a high-performance, low-voltage CMOS octal buffer designed to provide efficient interfacing to high-speed communication, computing, and networking applications. This device is part of the LCX range, which is characterized by its low power consumption and high noise immunity, suitable for 3.3V operation while maintaining 5V tolerant inputs.

The MC74LCX244DTEL features eight non-inverting buffers with 3-state outputs, which makes it ideal for driving bus lines or buffering memory address registers. Its 3-state outputs ensure that multiple devices can share a common bus without interference, as the outputs can be placed in a high-impedance state.

Constructed with advanced silicon gate CMOS technology, the MC74LCX244DTEL provides a significant reduction in power consumption compared to standard CMOS integrated circuits, especially when in the quiescent state. This makes it a preferred choice for battery-operated and power-sensitive applications.

The device's inputs can tolerate voltages up to 5V, regardless of the operating voltage, allowing for a smooth transition from 5V to 3.3V systems without the need for additional level shifters. This feature is particularly useful in mixed-voltage environments and when interfacing with legacy components.

ON Semiconductor ensures that the MC74LCX244DTEL is equipped with over-voltage tolerance on the inputs, which not only protects the device from unintentional voltage spikes but also extends its longevity and reliability. The device is also characterized by its low-voltage operation, which minimizes power dissipation without compromising speed.

The MC74LCX244DTEL comes in a TSSOP-20 package, which is optimized for reduced space on printed circuit boards, making it a suitable option for compact and high-density electronic designs. Its operating temperature range from -40°C to +85°C guarantees stable performance across various environmental conditions.

In summary, the ON Semiconductor MC74LCX244DTEL is a versatile, low-power, and robust octal buffer that delivers high-speed operation with 5V tolerant inputs, making it an excellent choice for interfacing and driving bus lines in modern electronic systems.
