PIN DESCRIPTIONS
INPUTS
D0, D1, D2, D3 (Pins 14, 13, 12, 11)
4–bit data inputs. Data on these pins, when enabled by the
Data–Enable Controls, are entered into the flip–flops on the
rising edge of the clock.
CLOCK (Pin 7)
Clock input.
OUTPUTS
Q0, Q1, Q2, Q3 (Pins 3, 4, 5, 6)
3–state register outputs. During normal operation of the
device, the outputs of the D flip–flops appear at these pins.
During 3–state operation, these outputs assume a high–
impedance state.
CONTROL INPUT
Reset (Pin 15)
Asynchronous reset input. A high level on this pin resets all
flip–flops and forces the Q outputs low, if they are not already
in high–impedance state.
DE1, DE2 (Pins 9, 10)
Active–low Data Enable Control inputs. When both Data
Enable Controls are low, data at the D inputs are loaded into
the flip–flops with the rising edge of the Clock input. When
either or both of these controls are high, there is no change in
the state of the flip–flops, regardless of any changes at the D
or Clock inputs.
OE1, OE2 (Pins 1, 2)
Output Enable Control inputs. When either or both of the
Output Enable Controls are high, the Q outputs of the device
are in the high–impedance state. When both controls are
low, the device outputs display the data in the flip–flops.
