REVISION HISTORY
The following represent the key differences between the 10/26/04 and 07/05/05 version of the DS87C550
data sheet. Please review this summary carefully.
1. Added Pb-free part numbers to the Ordering Information table.
The following represent the key differences between the 06/14/99 and the 10/26/04 version of the
DS87C550 data sheet. Please review this summary carefully.
1. Preliminary status was removed.
2. AC and DC Electrical Specifications updated with final characterization data.
3. Added tAVLL2 parameter.
4. Clarified that the typical oscillator fail detect threshold is 40kHz.
The following represent the key differences between the 06/16/98 and the 06/14/99 version of the
DS87C550 data sheet. Please review this summary carefully.
1. Corrected minor typographical errors on pages 3, 5, 7, 9, 17, 20, 21, 22, 26 and 33.
2. Added standard “Absolute Maximum Ratings” notation.
3. Added AID Specification conditions (VCC = 5V
± 10%, 0°C to +70°C).
4. Updated port 5’s VOL and IL specification.
