Product Overview: MC74VHC244MEL from ON Semiconductor

The MC74VHC244MEL is an advanced high-speed CMOS octal buffer/line driver designed to meet the requirements for higher speed needs in modern electronic applications. Manufactured by ON Semiconductor, a leader in the industry, this integrated circuit is part of the VHC family, which is known for its low power consumption and high noise immunity equivalent to other CMOS technologies.

Designed to be used as an interface between two different voltage domains, this device features octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs allow for connection to a bus-oriented system. They can drive bus lines or buffer memory address registers with the high-performance of CMOS technology. This makes the MC74VHC244MEL suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working as a transient-energy suppressor to protect other sensitive circuitry.

The MC74VHC244MEL operates at a voltage range from 2.0V to 5.5V, making it compatible with TTL levels, while its inputs tolerate voltages up to 5.5V, allowing it to be used in 5V environments without concern for input overvoltage. This feature is particularly beneficial in mixed-voltage applications. Additionally, the device has a high drive current of ±24 mA at the outputs, ensuring good signal integrity and strong driving capabilities.

The device is offered in a surface-mount package, specifically the SOIC-20 (Wide Body) package, which is well-suited for space-constrained applications. Its operating temperature range from -55°C to +125°C ensures reliability across various environmental conditions. The MC74VHC244MEL is also characterized for operation from -40°C to +85°C, providing a robust solution for industrial and automotive applications where temperature extremes are common.

In summary, the MC74VHC244MEL from ON Semiconductor is a versatile, robust, and high-performing component that provides an efficient solution for buffering and driving bus lines in a wide range of electronic systems. Its compatibility with various voltage levels, high noise immunity, and strong output drive characteristics make it a preferred choice for designers looking to optimize their high-speed digital interfaces.
