Working Principles

The CY74FCT480BTSOCT is a logic level shifter that facilitates communication between devices operating at different voltage levels. It utilizes a combination of input buffers, level shifters, and output buffers to ensure proper voltage translation.

When an input signal is received, the input buffer adjusts the voltage level to match the internal logic levels of the IC. The level shifter then converts the voltage to the desired output level, which is typically CMOS. Finally, the output buffer amplifies the signal and drives it to the output pin.

The output enable (OE) pin allows the user to control the output state. When OE is high, the outputs are enabled, and when OE is low, the outputs are disabled.
