CLK

Clock: On a rising edge of CLK, the DN inputs are transferred to the QN outputs. While

CLK is high or low, the QN outputs do not change regardless of the state of the data

inputs. See truth table.

Enable. This active-high input enables the device. When low, inputs are ignored and

updates to the nonvolatile cells are prevented. When high, the device operates
