Logic - Gates and Inverters

NC7SPU04L6X is a single-channel, low-voltage level shifter specifically designed to safely transfer signals between two nodes of different supply voltages in a variety of applications. It is based on NXP\'s advanced CMOS process technology, incorporating an high-threshold CMOS input stage followed by an NMOS output stage for improved reverse transfer characteristics.

Application Field

NC7SPU04L6X is ideally used for transferring digital data signals between devices running on different power supplies. It can also be used for digital communication systems, as it is designed to safely transfer signals up to 3.3V both up and down, allowing a maximum resistor network of 1.2K Ohms. The flexible design of the device allows for a variety of voltage configurations, making it useful in diverse applications.

Working Principle

The NC7SPU04L6X uses two main components in order to control the voltage level shifter, an NMOS transistor and a resistor network. The NMOS transistor is connected between the two nodes and acts as a switch, controlling the data flow between them. When an input signal is applied at one of the nodes, the voltage rises and the transistor is activated, allowing data to flow in the appropriate direction. This transferred data can then be received by the output node, which is held at a consistent voltage level, allowing for the safe and reliable transmission of data across the system.

The resistor network is also used to control the voltage level shifter. Its value is set to be the maximum allowable for the nodes, and its purpose is to provide a current limiting path for the system. This helps protect the components from damage due to excessive currents being drawn from the system. The resistor network can be set to different values depending on the needs of the system.

The NC7SPU04L6X is an ideal solution for many different types of applications as its high-threshold CMOS input stage and its NMOS output stage provide improved reverse transfer characteristics. Its flexibility, combined with its low voltage programming and detection capabilities, make it the perfect choice for a variety of signals across different power supply systems.
