They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. A buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high or low logic levels) or a high-impedance state. The outputs are also in the high-impedance state during power-up and power-down conditions. The outputs remain in the high-impedance state while the device is powered down. 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. 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 PRE LE 2D 1D SN54ABT843 . . .

Previously stored data can be retained or new data can be entered while the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, 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 SN54ABT843 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74ABT843 is characterized for operation from –40°C to 85°C.
