ISL54102CQZ

The ISL54102CQZ is a high-voltage level shifter that translates digital input signals up to 15 volts to digital outputs up to 20 volts, a voltage level both sides of the data bus for communication between circuits on an integrated circuitchip. It is well-suited for a variety of interface applications such as communications between rail-to-rail circuity or between low voltage logic circuits and high voltage drive circuits.

The ISL54102CQZ is designed to reduce power consumption, improve performance, and reduce system noise. It uses a power save Buffer to reduce power consumption and a match Shift Buffer to reduce system noise. The high-voltage level shifter consists of three differential input buffers, a tri-level output circuit, and level translators.

The input buffers isolate the input logic levels from the output logic levels. They are designed to have low input leakage, wide input common-mode voltage range,and low power consumption. The outputs are short-circuit current limited, so the outputs can drive in the range from 3V to 20V up to the maximum power supply voltage rating. The tri-level output circuit provides the necessary level shifting for the I/O lines. It is designed for low power consumption and low output noise.

The level translators provide the level shifting from the inner logic levels to the outside logic levels. They are typically used for low current applications and high speed operations. They buffer the high voltage outputs so that the signals are not affected by loading. In addition, they provide high impedance between the input and the output, so that the inputs are not current limited.

In addition to its ability to level shift between complementary logic levels, the ISL54102CQZ also offers a wide range of features to enhance system performance. These include on-chip termination and slew rate control, on-chip frequency compensation, and reduced power consumption. On-chip termination and slew rate control eliminates external resistors and capacitors and minimizes power consumption. Frequency compensation eliminates ringing and reduces the noise in the system. Reduced power consumption helps to minimize system heating.

The ISL54102CQZ is an excellent choice for high speed interface applications where the need for high data rates and the restricted space requirements are critical. Its high level shifting and wide range of features make it an ideal choice for high speed data transmission, gate drive, load switch, and similar applications.
