CD4042BD .

产品概述

The CD4042BD is a quad CMOS clocked D-type Latch IC contains 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.
