Data sheet acquired from Harris Semiconductor

CD4042B 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 output until an opposite CLOCK transition occurs.

The CD4042B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffixes), 16-lead dual-in-line plastic package (E suffix), 16-lead small-outline packages (D, DR, DT, DW, DWR, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
