STMicroelectronics 74VHCT05ATTR Hex Inverter

The 74VHCT05ATTR is a high-speed CMOS hex inverter manufactured by STMicroelectronics, designed to address the needs of modern electronic systems with its advanced features and robust performance. This device is part of the VHCT family, which is known for its low power consumption and high noise immunity equivalent to the standard CMOS integrated circuits.

The 74VHCT05ATTR is specifically engineered to provide inverting buffer functions with open-drain outputs, allowing for wired-OR logic gates configurations. Each of the six inverters is capable of driving 3-state bus lines or other high-capacitive loads, making it a versatile choice for a wide array of applications, including bus-oriented systems.

Key features of the 74VHCT05ATTR include:

• High-Speed Performance: The device offers fast propagation delays, ensuring quick response times suitable for high-speed logic operations.
• Low Power Consumption: It operates with a very low quiescent current, contributing to energy-efficient designs and longer battery life in portable applications.
• High Noise Immunity: The VHCT logic level creates a high noise threshold, making the device tolerant to electrical noise and stable under varying conditions.
• Wide Operating Voltage Range: The 74VHCT05ATTR can function over a broad voltage range from 4.5V to 5.5V, accommodating various system power requirements.
• Open-Drain Outputs: These outputs allow for direct connection to other open-drain or push-pull outputs, providing flexibility in interfacing with different logic levels.

The device is offered in a thin shrink small outline package (TSSOP) with 14 leads, under the part number 74VHCT05ATTR. This compact package is suitable for space-constrained applications without compromising on performance or reliability.

Thanks to its compatibility with TTL outputs, the 74VHCT05ATTR can be used in mixed 5V and 3.3V environments, supporting legacy systems while enabling integration with newer technology. Whether it's for use in telecommunications, computing, or consumer electronics, the 74VHCT05ATTR from STMicroelectronics is a reliable and efficient solution for designers looking to implement high-performance inverting functions in their circuits.
