10-Bit Buffers/Drivers With 3-State Outputs



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

The 3-state control gate is a 2-input NOR such that if either output-enable ( or ) input is high, all ten outputs are in the high-impedance state.

The SN74ALS29827 provides true data and the SN74ALS29828 provides inverted data at their respective outputs.

The SN74ALS29827 and SN74ALS29828 are characterized for operation from 0°C to 70°C.


  • Functionally Equivalent to AMD's AM29827 and AM29828
  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
  • pnp Inputs Reduce dc Loading
  • Data Flow-Through Pinout (All Inputs on Opposite Side From Outputs)
  • Power-Up High-Impedance State
  • Package Options Include Plastic Small-Outline (DW) Packages and Standard Plastic (NT) 300-mil DIPs
