The HCF4042BE is a monolithic integrated circuit fabricated in metal oxide semiconductor technology. The HCF4042BE types contains four latch circuit, each strobes by a common clock. Complementarybuffered 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 transferredto 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.
