ON Semiconductor MC74ACT14DR2 Description

The MC74ACT14DR2 from ON Semiconductor is a high-performance, hex inverter with Schmitt-trigger inputs that is a part of the 74ACT series. This integrated circuit is designed to operate with an advanced high-speed CMOS technology and is optimized for exceptional noise immunity and stable output. The device is particularly well-suited for wave shaping and noise-critical applications where input signals may not be clean or may have slow transitions.

Each inverter within the MC74ACT14DR2 has a Schmitt-trigger input that enables the transformation of slowly changing input signals into sharply defined jitter-free output signals, adding to its versatility in various digital applications. This feature is particularly useful in applications that require signal conditioning, such as debouncing switches or reading noisy sensors.

The MC74ACT14DR2 operates over a broad voltage range of 4.5V to 5.5V, making it compatible with TTL levels, while offering the benefits of CMOS technology, such as low power consumption and reduced heat dissipation. The low power consumption is a significant advantage in battery-operated or power-sensitive devices.

This device is available in a compact SOIC-14 package, which is ideal for space-constrained applications. The MC74ACT14DR2 offers a propagation delay time of approximately 8ns at 5V, which allows for high-speed operation that is essential in modern digital circuits. Furthermore, its outputs can drive up to 24mA, providing good current sinking capabilities for interfacing with LEDs, relays, or other output devices.

The MC74ACT14DR2 is characterized for operation from -55°C to 125°C, making it suitable for industrial and automotive applications that require reliable performance under extreme temperature conditions. Its robust design ensures that the device can withstand the rigors of harsh operating environments.

In summary, ON Semiconductor's MC74ACT14DR2 hex inverter with Schmitt-trigger inputs is a versatile, high-performance component that offers reliable operation, low power consumption, and high noise immunity. Whether used in signal processing, timing circuits, or digital logic applications, this device provides a solid solution for designers looking to enhance the performance and stability of their electronic systems.
