pF
1. For propagation delays with loads other than 50 pF, see Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).
2. Information on typical parametric values can be found in Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).
Typical @ 25°C, VCC = 5.0 V

pF
* Used to determine the no–load dynamic power consumption: PD = CPD VCC2f + ICC VCC. For load considerations, see Chapter 2 of the
Motorola High–Speed CMOS Data Book (DL129/D).
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 ad-
dress of the selected input (see the Function Table).
Strobe (Pin 7)
Strobe. This input pin must be at a low level for the se-
lected 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.
