The 74LVC2G07GXZ is a member of the Low-Voltage Single-Buffer Gate series. This type of chip is classified as a category of Logic - Buffers, Drivers, Receivers, Transceivers. The main purpose of this series of chips is to increase drive capability, provide receiver input parameters, and to create semiconductor paths between one or more logic signals. These devices are designed to provide isolation and amplify voltage levels between inputs, outputs, subsystems and busses.

Application Field

The 74LVC2G07GXZ is typically used in low-voltage, high-speed logic systems. Due to its small size, low-power consumption and high-speed capabilities, this series of chips is widely used in automation, avionics, communications, consumer electronics, instrumentation, medical, and military applications. This device is also great for use in automotive designs and may be used in applications where protection from electromagnetic interference (EMI) is needed.

Working Principle

The 74LVC2G07GXZ is designed to operate as a single-buffer gate, typically with 3-state outputs. The device contains two input buffers, each with a Schmitt-trigger action. This Schmitt-trigger input provides noise filtering and is also enabled to operate in a rail-to-rail manner. The device also contains two output transistors which are both interconnected. This interconnection enables the outputs to remain in the same logic state when the device is in the active state.

When one of the inputs is at a high logic level, this forces both outputs to the same state. This creates the characteristic of the latch; if a low-level signal is then applied to the second input, this will cause the outputs to switch. The duration of the logic-switch is determined by the amount of input signal transitions, the values of the pull-up and pull-down resistors in the circuit, as well as the switching time delays of the device.

The 74LVC2G07GXZ also contains two symmetrical Schottky diodes, which are inserted to protect the gate inputs from static charge damage. To enhance output signal control, the device also has active low-level output enable. This pin is typically used to enable or disable the output level by pulling the low-level input signal to a low-level state.

This series of chip is also designed with an input hysteresis option. This feature provides an extra benefit for applications that require improved noise immunity. With this feature, the output state will remain unchanged as long as the input signal remains within the hysteresis window. This hysteresis window is typically specified as a fixed voltage between the two inputs.

Overall, the 74LVC2G07GXZ is an excellent choice for a wide range of logic applications. This series of chip is ideal for low-voltage designs due to its small size, low-power consumption and high-speed capabilities. Its many features make it a great choice for applications requiring isolation, noise filtering, protection from static, and improved output level control.
