tube. The pin is also attached to any of the Raspberry Pi's gpio ports. OE is the output enable PIN, which is also common in other chips. The function is to control whether the data in the latch is ultimately output to the Q0-Q7 output pin. Low-power output, high-power normally not output (neither high-level, nor low-level but high-impedance state, no power). In order to facilitate direct connection to GND, this example keeps the output data low.
