Test Specifications
Note:
The minimum and maximum values in Table 5 through Table 13 on page 26 and Figure 11 on
page 27 through Figure 26 on page 34 represent the performance specifications of the LXT905.
These specifications are guaranteed by test, except where noted by design. Minimum and
maximum values in Table 7 through Table 13 on page 26 apply over the recommended operating
conditions specified in Table 6.
For all Quality and Reliability issues (for example, parts packaging and thermal specifications),
please send your questions to Intel at the following e-mail address: qr.requests@intel.com.

1. Typical values are at 25 °C, are for design aid only, are not guaranteed, and are not subject to production
testing.
2. Limited functional tests are performed at these input levels. The majority of functional tests are performed
at levels of 0V and 3V. This applies to all inputs except TPIP and TPIN.
