20. REVISION HISTORY
REVISION
DESCRIPTION
070904
New product release.
032405
Updated Table 2-1 and Table 2-2.
Replaced the older recommended LIU circuits in Section 13.8 with newer versions (Figure 13-4
and Figure 13-5, Table 13-1 and Table 13-2).
Modified the value of tDD in Table 19-5. Added timing information to Table 19-5 and updated
Figure 19-11.
081105
Corrected the bit order for the TCPR register. Bits 6 and 7 were reversed. Bits 3 and 4 were
reversed.
Corrected the polarity of the TAIS pin description for hardware mode operation (pages 18 and
28). The register control bit description for LIC2.4 is correct.
Added thermal values to Table 18-2.
101805
Changed Section 13.4 to read “2.048 x 2
N (where N = 1 to 3)” instead of “2.048 x N (where N
= 1 to 4).”
Edited Figure 3-4 to show 12.8MHz clock option and added references throughout relevant
sections of the document.
Added JACKS1 bit to LIC2.7—This feature is available in Rev B1 and later.
022806
Clarified the open circuit and short circuit wording in Sections 13.3.1 and 13.3.2 and SR1 bits 1
and 2.
053107
(Page 48) Removed reference to E1RCR and E1TCR bit 3 (this bit functionality has been
moved to the MCREG).
100507
(Pages 108–109) In the Absolute Maximum Ratings (Section 18), added Note 1: Specifications
at -40
°C are guaranteed by design GBD and not production tested. to Operating Temp Range
for DS26503LN. Renumbered notes for Table 18-1 to Table 18-5.
121707
(Page 16) Clarified RITD and TITD descriptions.
(Page 19) For E1TS description, changed 0 = 120
Ω and 1 = 75Ω to 0 = 75Ω and 1 = 120Ω.
(Page 82) Corrected Note 2 in the LIC1[7:5] register description to include TT2 along with TT0
and TT1.
