‡ Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51, except for through-hole packages, which use a trace length of zero.

These  SN54ABT2827 10-bit buffers or bus drivers provide a high-performance bus interface for wide data paths or buses carrying parity.

The 3-state control gate of SN54ABT2827  is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all ten outputs are in the high-impedance state. The SN54ABT2827 provide true data at their outputs.

To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.The outputs, which are designed to source or sink up to 12 mA, include equivalent 25-  series resistors to reduce overshoot and undershoot.The SN54ABT2827 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ABT2827 is characterized for operation from 40°C to 85°C.
