Data outputs are indicated by Q followed by a number. One-inverter oscillators are indicated by X0 and X1 pins, where X0 is the inverters' output and X1 is the input. If I happen not to know which is which, the pins are indicated by X1 and X2. A crystal oscillator can then be made using X0 and X1. The clock is positive-edge triggered.
Complementary outputs are available.
Analog switches generally are bidirectional, and inputs and outputs can therefore be reversed. When the S inputs are taken as a binary number, the value indicates which switch is selected.
