Application Scenarios & Design Considerations

Octal Buffer/Driver with 3-State Outputs

Alternative Part Number

  • 74AUC244BQ,115 --: Same AUC-family octal buffer/line driver in a comparable small package, offering similar low-voltage high-speed performance.
  • 74AUC244PW,118 --: AUC-series octal buffer with equivalent logic function and low propagation delay, suitable drop-in for level-shifting and clock distribution.
  • SN74AUC244RGYR --: Same AUC family octal buffer from the same vendor in the same RGY package, differing only in the 'H' bus-hold feature, making it a close functional substitute.
  • 74AUC244RGYR --: Same AUC-family octal buffer with equivalent 0.8V-2.7V operation and RGY QFN package, pin-compatible functional drop-in.
  • 74AUP2G244GS --: Low-power dual buffer alternative in a small package; usable when fewer channels are needed, though channel count and package differ.
