DB, DW, OR NT PACKAGE (TOP VIEW) OE 1D 2D 3D 4D 5D 6D 7D 8D 9D CLR GND These 9-bit flip-flops feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers. With the clock-enable (CLKEN) input low, the nine D-type edge-triggered flip-flops enter data on the low-to-high transitions of the clock. Taking CLKEN high disables the clock buffer, thus latching the outputs. Taking the clear (CLR) input low causes the nine Q outputs to go low, independently of the clock. 24 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 12 13 VCC 1Q 2Q 3Q 4Q 5Q 6Q 7Q 8Q 9Q CLKEN CLK SN54ABT823 . . .

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 pullup components. When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN54ABT823 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74ABT823 is characterized for operation from –40°C to 85°C.
