PIN DESCRIPTION
NAME
I/O
DESCRIPTION
D
I
D flip-flop data inputs
CLR
I
When CLR is low and OE is low, Q outputs are low. When CLR is high, data can be entered into the register.
CP
O
Clock pulse for the register. Enters data into the register on the low-to-high clock transition.
Y
O
Register 3-state outputs
EN
I
Clock enable. When EN is low, data on the D input is transferred to the Q output on the low-to-high clock transition. When
EN is high, the Q outputs do not change state, regardless of the data or clock input transitions.
OE
I
Output control. When OE is high, the Y outputs are in the high-impedance state. When OE is low, true register data is present
at the Y outputs.
