54F 74F563 Octal D-Type Latch with TRI-STATE Outputs May 1995 54F 74F563 Octal D-Type Latch with TRI-STATE Outputs General Description The ’F563 is a high-speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs This device is functionally identical to the ’F573 but has inverted outputs Features Y Y Y Inputs and outputs on opposite sides of package allowing easy interface with microprocessors Useful as input or output port for microprocessors Functionally identical to ’F573 Commercial 74F563PC Military Package Number N20A Package Description

contains eight D-type latches with TRI-STATE output buffers When the Latch Enable (LE) input is HIGH data on the Dn inputs enters the latches In this condition the latches are transparent i e a latch output will change state each time its D input changes When LE is LOW the latches store the information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE The TRI-STATE buffers are controlled by the Output Enable (OE) input When OE is LOW the buffers are in the bi-state mode When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches Inputs OE H H H H L L L LE X H H L H H L D X L H X L H X Function Table Internal Q X H L NC H L NC Output O Z Z Z Z H L NC High Z High Z High Z
