Working Principles

The 74AHC244PW-Q100,11 is an octal buffer/line driver IC that amplifies and buffers digital signals. It operates using non-inverting logic, meaning the output signal follows the input signal without any inversion. The IC is designed to work with a wide range of input voltages, making it compatible with both CMOS and TTL logic families.

The Schmitt-trigger action on all inputs ensures robust and noise-immune operation. When the output enable (OE) pin is low, the IC is enabled, allowing the input signals to pass through and appear at the corresponding output pins. When the OE pin is high, the outputs are in a high-impedance state, effectively disconnecting them from the rest of the circuit.
