PIN DESCRIPTIONS
INPUTS
D0, D1, … , D7 (Pins 4, 3, 2, 1, 15, 14, 13, 12)
Data inputs. Data on any one of these eight binary inputs
may be selected to appear on the output.
CONTROL INPUTS
A0, A1, A2 (Pins 11, 10, 9)
Address inputs. The data on these pins are the binary
address of the selected input (see the Function Table).
Strobe (Pin 7)
Strobe. This input pin must be at a low level for the
selected data to appear at the outputs. If the Strobe pin is
high, the Y output is forced to a low level and the Y output
is forced to a high level.
OUTPUTS
Y, Y (Pins 5, 6)
Data outputs. The selected data is presented at these pins
in both true (Y output) and complemented (Y output) forms.
