ON Semiconductor MC74VHCT244ADT

The ON Semiconductor MC74VHCT244ADT is a high-performance, octal bus buffer that operates as a non-inverting 3-state buffer. Designed to interface with 5V systems, this integrated circuit ensures a high level of performance in a wide range of applications, from telecommunications to computing systems. The device is part of the VHCT family, which is known for its high noise immunity and low power consumption, making it an excellent choice for portable and battery-operated equipment.

This particular model comes in a TSSOP-20 package, which is a space-saving and surface-mountable solution that is well-suited for densely packed circuit boards where real estate is at a premium. The MC74VHCT244ADT is equipped with eight buffers and 3-state outputs that can be controlled by two output enable (OE) pins. This feature allows for greater flexibility in bus management and signal routing within complex electronic systems.

The device has a wide operating voltage range from 4.5V to 5.5V, which allows for a margin of error in power supply stability and ensures compatibility with standard 5V logic levels. Its fast propagation delay and transition times are essential for high-speed data transmission, minimizing signal lag and improving overall system responsiveness.

The MC74VHCT244ADT is characterized for operation from -55°C to +125°C, which means it can withstand extreme environmental conditions, making it suitable for industrial and automotive applications that require reliable performance under harsh conditions. Additionally, its inputs are tolerant to up to 5.5V, allowing for interface flexibility with higher-voltage logic signals without risk of damage.

ON Semiconductor's commitment to quality is evident in the MC74VHCT244ADT, which is manufactured to meet the stringent requirements of the automotive industry's AEC-Q100 standards. This ensures that each device is capable of withstanding the rigorous demands of automotive applications, where reliability and durability are paramount.
