The M74HC14YTTR is a member of the M7 family of devices designed and manufactured by STMicroelectronics, based on silicon CMOS technology and dielectric optoelectronics. It is widely used in digital communication, industrial automation and other fields. This article introduces the application field and working principle of the M74HC14YTTR.

Application Field of M74HC14YTTR

The M74HC14YTTR is a six-input, single-gate CMOS logic device. It is intended for use in general-purposes, automotive, railroad and aerospace applications. In addition, it can also be used in timing applications and various other applications requiring low-power consumption, fast switching, high gate density and high gate speed. This device has a wide common-mode range, which makes it suitable for differential operations. It is also capable of handling large differential inputs. Additionally, the M74HC14YTTR comes with a number of features to improve its overall electrical ride-through performance.

The device is designed to handle both static and dynamic conditions. It is capable of operating on voltage levels ranging from 5-25V, which makes it ideal for operating in low voltage systems. In addition, the device is also capable of operating in temperatures ranging from -40 to +85 degrees Celsius. This makes it suitable for use in military and aerospace applications.

The device has good noise immunity, which makes it suitable for use in high-noise environments. The device is also designed to reduce power consumption and provide low power dissipation. This makes it ideal for use in battery-powered applications.

The M74HC14YTTR is available in various package configurations, including leaded, gullwing and surface-mount. This makes it suitable for use in both through-hole and surface-mount applications.

Working Principle of M74HC14YTTR

The M74HC14YTTR is classified as a single-gate CMOS logic device, which means it is designed to use two-state logic signals. When the input signal at a particular gate goes high (logic 1), the output signal at the same gate goes high as well. When the input signal at the gate goes low (logic 0), the output signal at the same gate goes low.

The M74HC14YTTR contains six independent inputs and six independent outputs. Each input is connected to the corresponding output by an internal MOSFET functioning as an inverter. When the input signal at one gate is low (logic 0), the internal n-channel MOSFET is activated, allowing current to flow from the corresponding output to ground. When the input is high (logic 1), the internal p-channel MOSFET is activated, allowing current to flow through the output.

The M74HC14YTTR provides excellent noise immunity and high speed performance. Its logic level noise immunity of 45V/us minimizes propagation delays and fuzzy outputs. Its propagation delay of 17ns (at 5V), and a maximum switching speed of 180 MHz make it ideal for high speed applications.

The M74HC14YTTR provides superior radiation hardness performance, and its typical radiation hardness of 20 kRad makes it ideal for use in medical and aerospace applications. Additionally, it comes with a wide operating temperature range of -40 to +85 degrees Celsius and a low supply current of 1.5mA.

Conclusion

The M74HC14YTTR is a six-input single-gate CMOS logic device designed for a wide range of applications. It is suited for use in static and dynamic conditions, and it has a wide operating temperature range from -40 to +85 degrees Celsius. The device has excellent noise immunity and high speed performance, and its logic level noise immunity of 45V/us provides good propagation delay and fuzzy outputs. Additionally, its maximum switching speed of 180 MHz and typical radiation hardness of 20 kRad make it suitable for high speed applications.
