These 10-bit buffers and bus drivers providehigh-performance bus interface for wide datapaths or buses carrying parity.
The 3-state control gate is a 2-input AND gate withactive-low inputs so that if either output-enable(OE1 or OE2) input is high, all ten outputs are inthe high-impedance state. The outputs are also inthe high-impedance state during power-up andpower-down conditions. The outputs remain in thehigh-impedance state while the device is powereddown.
The SN54BCT29827B is characterized foroperation over the full military temperature rangeof −55°C to 125°C. The SN74BCT29827B ischaracterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, andfunctional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is notimplied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1:The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
