Полупроводники - Микросхемы\Логика\Триггеры-защелкиThe SN74F573DW is an octal transparent D Latch with 3-state outputs. It is designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers. The eight latches of the F573 are transparent D-type latches. While the latch enable input is high, the Q outputs follow the data (D) inputs. When the latch enable is taken low, the Q outputs are latched at the logic levels set up at the D inputs. A buffered OE\ input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a 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 need for interface or pull-up components. • Full parallel access for loading• Buffered control inputs
