Description
CD4042BMS 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.

CL
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
deï¬ned 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.
