For DESCRIPTION POLARITY = 0 the transfer occurs during the 0 The HCF4042B is a monolithic integrated circuit CLOCK level and for POLARITY = 1 the transfer fabricated in Metal Oxide Semiconductor occurs during the 1 CLOCK level. The outputs technology available in DIP and SOP packages. follow the data input providing the CLOCK and The HCF4042B types contains four latch circuit, POLARITY levels defined above are present. each strobes by a common clock. Complementary When a CLOCK transition occurs (positive for buffered outputs are available from each circuit. POLARITY = 0 and negative for POLARITY = 1) The impedance of the n and p channel output the information present at the input during the devices is balanced and all outputs are electrically CLOCK transition is retained at the outputs until identical.
