Working Principles

The IDT74FCT540CTPYG8 is a non-inverting buffer/line driver that operates as a logic level shifter. It accepts logic signals from one voltage level and translates them to another voltage level, allowing seamless communication between different logic families. The device uses CMOS technology, which provides high-speed operation and low power consumption.

The inputs (A1-A8) are compatible with a wide range of logic families, including TTL, LVTTL, and CMOS. The outputs (Y1-Y8) are capable of driving ±24mA, ensuring strong signal integrity even over long distances or when driving capacitive loads.

The OE (Output Enable) pin controls the output state of the device. When OE is high, the outputs are active and reflect the input signals. When OE is low, the outputs are in a high-impedance state, allowing other devices to drive the shared bus.
