Working Principles

The 74LVC2G240DC-Q100H is a CMOS-based buffer/driver IC that operates as a voltage level shifter and signal amplifier. It consists of two non-inverting buffer/driver circuits with 3-state outputs. The inputs are compatible with both TTL and CMOS logic levels, allowing seamless interfacing between different logic families.

When the Output Enable (OE) pin is low, the outputs (Y1 and Y2) are active and reflect the input signals (A1 and A2). When OE is high, the outputs enter a high-impedance state, effectively disconnecting them from the bus and allowing other devices to drive the bus lines.

The IC operates within a wide supply voltage range, making it suitable for various low-voltage systems. It provides fast propagation delay, ensuring efficient signal transmission. Additionally, its low power consumption and small package size make it ideal for space-constrained applications.
