At this time the total VCC appears across resistor R1.

ON Semiconductor

There are four and gates in the chip and each gate have two inputs, hence the name quadruple 2 input and gate. This LED is connected to detect the state of output. This enables the use of current limiting resistors to interface inputs to voltages in excess of vcc. Because total VCC appears across transistors the drop across resistor R1 will be zero. With that the drop across resistor R1 will be zero.
