Alternative Part Number

  • P82284 --: Original Intel 82284 clock generator for 80286 systems; the Siemens SAB82284 is a licensed second-source of this exact Intel device, so it is a direct functional and pin-compatible replacement.
  • 82C284 --: CMOS version of the 82284 clock generator with the same function and pinout, offering lower power consumption and widely available as a drop-in substitute.
  • UPD71011C --: Second-source 82284-compatible clock generator used in 80286-based designs; functionally equivalent and pin-compatible with the Siemens part.
