CD4042BM/CD4042BC Quad Clocked D Latch
General Description
The CD4042BM/CD4042BC quad clocked ‘‘D’’ latch is a
monolithic complementary MOS (CMOS) integrated circuit
constructed with P- and N-channel enhancement mode
transistors. The outputs Q and Q either latch or follow the
data input depending on the clock level which is pro-
grammed by the polarity input. For polarity
e
0; the informa-
tion present at the data input is transferred to Q and Q
during 0 clock level; and for polarity
e
1, the transfer occurs
during the 1 clock level. When a clock transition occurs
(positive for polarity
e
0 and negative for polarity
e
1), the
information present at the input during the clock transition is
retained at the outputs until an opposite clock transition oc-
curs.
