Working Principles

The 74VHC16373TTR operates based on the principles of flip-flops. Each latch within the IC can store a single bit of data. When the latch enable (LE) input is high, the data at the corresponding data (D) input is transferred to the latch's output. The outputs are controlled by the output enable (OE) input. When OE is low, the outputs are active and reflect the stored data. When OE is high, the outputs are in a high-impedance state.
