Working Principles
The 74ABT620D,602 is based on Advanced BiCMOS Technology (ABT), which combines the advantages of both bipolar and CMOS technologies. It operates as a non-inverting buffer, meaning that the input signal is reproduced at the output without any inversion. The IC is designed to drive high-capacitance loads and provide strong output current capabilities.
The output enable (OE) pin controls the output state. When OE is low, the outputs are active and reflect the input data. Conversely, when OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the external circuit.
