DESCRIPTION
OCTAL TRANSPARENT D-TYPE LATCH WITH 3 STATE OUTPUTS A Pin Assignments While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the highimpedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pullup components. OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. These devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board lay
