74LVC573A - OCTAL TRANSPARENT D-TYPE LATCH

General Description

The 74LVC573A provides eight transparent D-type latches.

While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs.

NEW PRODUCT 74LVC573A Description OCTAL TRANSPARENT D-TYPE LATCH WITH 3 STATE OUTPUTS A Pin Assignments The 74LVC573A provides eight transparent D-type latches. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the 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.
