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 _{Inputs and outputs on opposite sides of package}
allowing easy interface with microprocessors
Y _{Useful as input or output port for microprocessors}
Y _{Functionally identical to ’F573}
