They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and SN54F573...FK PACKAGE (TOP VIEW) working registers. C The eight latches of the ′F573 are transparent 2D 1D OEVC1Q D-type latches. While the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. 3 2 1 20 19 3D 4 18 2Q When the latch enable is taken low, the Q outputs 4D 5 17 3Q are latched at the logic levels set up at the D 5D 6 16 4Q inputs. 6D 7 15 5Q A buffered output enable (OE) input can be used 7D 8 14 6Q 9 10 11 12 13 to place the eight outputs in either a normal logic state (high or low logic levels) or a high- D D EQ Q 8 N L8 7 impedance state. In the high-impedance state, the G 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 pullup components. The output enable (OE) input does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The SN54F573 is characterized for operation over the full military temperature range of −55°C to 125°C. The SN74F573 is characterized for operation from 0°C to 70°C.
