The MC74LVX14MELG is a member of the Texas Instruments 74LVX family of low-voltage CMOS(LV-CMOS) logic gates.LV-CMOS is the perfect choice for low-voltage applications such as portable devices, where battery efficiency and low supply voltage are at a premium. Logic circuit design is made easy by these gates because they have very low power consumption and can run at signal speeds as high as 160MHz with little or no external component layout needed.

Application Field

The MC74LVX14MELG is a 14-input inverter gate that is designed for low-voltage (1.65V - 3.6V) applications. It\'s suitable for both digital and analog designs. It has low propagation delays (1.4ns @ 1.2V), high speed (CIN 13pf max.), and high noise immunity (15kV/us min. @ 1.2V). It can be used in digital designs to provide a wide variety of digital functions such as logic level conversion, logic buffering, and power supply protection. It also performs analog functions such as line receivers, signal conditioning, and signal regeneration.

Moreover, because it is a low-voltage device, it can be used to create logic circuits that are powered by battery sources such as solar panels and rechargeable batteries. This makes it perfect for use in mobile applications such as portable medical devices and remote control applications.

Working Principle

The MC74LVX14MELG utilizes CMOS technology, a method of combining transistors in a complementary fashion with both P-type and N-type transistors in the same chip. Essentially, the gate functions as a switch, turning off when a logic low (ground) is applied to the input and turning on when logic high (Vcc) is applied to the input. When the switch is on, the output will be the inverse of the input (high-to-low). This inverter gate is designed to be used with a single supply, meaning it can be powered by a single source of voltage, usually between 1.65V and 3.6V.

The gate\'s input voltage range is from 0V up to Vcc, meaning it will recognize any signal within that range as either a logic high (Vcc) or a logic low (ground). It\'s an asymmetric inverter, meaning that the lowest input will produce the highest output and vice versa.

The MC74LVX14MELG is an open-drain design, meaning that the output will always be in the same state (high or low) as the input signal, regardless of the other inputs. This makes it ideal for signal fan-out and low-noise switching environments.

The device is also equipped with Schmitt-trigger inputs, which are designed to reduce noise sensitivity and provide a guaranteed switching point. The Schmitt-trigger helps to eliminate the possibility of false triggering from noise on the signal line, giving the device a greater immunity to noise and better performance in noisy environments.

The MC74LVX14MELG is an excellent choice for low-voltage designs because of its low power consumption and its ability to run at signal speeds as high as 160MHz without any external component layout needed. It\'s suitable for use in both digital and analog designs, making it an ideal choice for portable devices and remote control applications. With its low propagation delays and low-noise immunity, it is perfect for signal fan-out and low-noise switching operations.
