Voltage converters

A variety of currently used components and the digital technology of their performance is forcing designers need to work on different power supply voltage levels. However, even if the power supply circuit devices provide everything necessary for the correct functioning of the section, it does not mean that the system will work correctly. You must still correctly selected the voltage converters that provide the appropriate voltage levels of digital signals by individual IP.

Logical levels, that is, the unit the unit is uneven

Systems theory in the field of digital methods of presentation state logic is extremely simple. In the most frequently used so-called positive logic – zero-low (L), and the voltage equal to the supply voltage (e.g., 3.3 V or 5 V) corresponds to a logical unit, i.e. a high (H). Enough of the theory; the practice, as usual, because much more complex. Each layout digital actually interpreterpath input voltage, arranged in a particular manufacturer's range, with the output signals, which under normal use should not go beyond a certain narrow range. However, if one layout (e.g., microcontroller) power supply would be 5V, and the second to 3.3 V is required use a voltage Converter (also called inverter logic levels), which not only provide reliable communication between the individual systems, but will also provide schemes with a low voltage supply from possible damage due to too high input voltage.

Types and parameters of converters levels of logical

Significant division of the voltage converters is based on which (how many) directions, these items can transmit digital signals. Many converters transmits digital signals only in a particular direction, although some designs can work properly regardless of which way information is transmitted (i.e. which system is the transmitter and the receiver). So work, among other things, a very simple but highly efficient voltage converters on the construction based on transistors TRANSISTORS low power. In addition to the work key any Converter parameters are: the number of channels, the allowable voltage levels on both sides, as well as the maximum frequency of transmitted signals and, in some cases, the time of the distribution (i.e. the delay between a change in the output signal relative to the corresponding change in input).

Voltage converters the store Botland

In this category you will find a number of very useful modules that are ideal for using in the circuits of the prototype, as in the target solutions. All voltage converters available in universal modules with easy connectors goldpin (wlutowanymi or designed for self-Assembly) and ready to use complete with wires connection, available in our store in practical sets. In addition to the converters designed to work with digital outputs and inputs, and we also have specialized modules that allow you to communicate with I2C. These modules (for example, PCA9306) take into account the specifics of the physical layer of the I2C interface and ensure a stable cooperation models of different supply voltages.
