The HCC/HCF4042B types contain four latch circuits, each strobed by a common clock.
Complementary buffered outputs are available from each circuit.
The impedance of the n- and p-channel output devices is balanced and all outputs are electrically identical.
Information present at the data input is transferred to outputs Q and Q during the CLOCK level which is programmed by the POLARITY input.
For POLARITY = 0 the transfer occurs during the 0 CLOCK level and for POLARITY = 1 the transfer occurs during the 1 CLOCK level.
The outputs follow the data input providing the CLOCK and POLARITY levels defined above are present.
When a CLOCK transition occurs (positive for POLARITY = 0 and negative for POLARITY = 1) the information present at the input during the CLOCK transition is retained at the outputs until an opposite CLOCK transition occurs.
