NTE9370
Integrated Circuit
HTL, Quad DType FlipFlop
Description:
Four Dtype flipflops utilizing a common clock line make up the NTE9370. Each flipflop has compli-
mentary passive pull up outputs with a single D input. This circuit is ideal as a quad latch for temporary
storage of 4bit 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.
