SN74AHC573PW

IC, OCTAL D LATCH, SMD, 74AHC573.

The SN74AHC573PW is an octal transparent D-type Latch with 3-state outputs. It is designed for 2 to 5.5V VCC operation. The 3-state outputs directly drive bus lines. When the LE input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched at the logic levels of the D inputs. A buffered OE input can be used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. In the high-impedance 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 pull-up components. OE\ does not affect the internal operations of the latches.
