Working Principles

The 74LVX244SJX is a logic level shifter that operates as a non-inverting buffer/line driver. It takes input signals from one logic level and provides corresponding output signals at the same logic level. The IC utilizes CMOS technology, allowing it to operate at high speeds while consuming low power.

The 3-state outputs of the IC enable the control of signal flow by enabling or disabling the output drivers. When the Output Enable (OE) pin is high, the outputs are active and reflect the input signals. Conversely, when OE is low, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.

Detailed Application Field Plans

The 74LVX244SJX finds applications in various fields where logic level shifting and buffering are required. Some specific application areas include:

  1. Microcontroller interfacing
