FK PACKAGE (TOP VIEW) 2D 1D OE VCC description The ’ACT564 are octal D-type edge-triggered flip-flops that feature 3-state outputs 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. 3D 4D 5D 6D 7D 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2Q 3Q 4Q 5Q 6Q 8D GND CLK 8Q 7Q On the positive transition of the clock (CLK) input, the Q outputs are set to the complements of the logic levels set up at the data (D) inputs. 1Q D D A buffered output-enable (OE) input places the eight outputs in either a normal logic state (high or low logic levels) 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. OE does not affect internal operations of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. The SN54ACT564 is characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74ACT564 is characterized for operation from –40°C to 85°C.
