BU4042B General Description
The BU4042B is a four-circuit D latch with a common clock line and separate data input terminals.
When the polarity input is set to "H", input (D) is presented to output (Q) as is, as long as the clock input is rising, and when the clock input falls, output (Q) holds input (D) at that point. While the clock input is falling, output (Q) does not change even if input (D) changes.
Also, if the polarity input is set to "L", input (D) is presented to output (Q) as is, as long as the clock input is at "L" level, and when the clock input goes to "H" level, latching takes place.
