SN74LV573ATDWR

八路透明D类锁存器与三态输出 OCTAL TRANSPARENT D-TYPE LATCH WITH 3-STATE OUTPUTS

DESCRIPON/ORDERING INFORMATION

The SN74LV573AT is an octal transparent D-type latch. When the latch-enable 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 output-enable 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 pullup components.
