NTE NTE9370

NTE9370
Integrated Circuit
HTL, Quad D–Type Flip–Flop
Description:
Four D–type flip–flops utilizing a common clock line make up the NTE9370. Each flip–flop has complimentary passive pull up outputs with a single D input. This circuit is ideal as a quad latch for temporary
storage of 4–bit binary numbers.
Data is transferred from D inputs to outputs when the clock line is low. With the clock line high, output
data is held and D inputs are ignored.
