Notes
1 Digital outputs drive purely capacitive loads to full output levels (VDDD, GNDD)
2 Percentage of the nominal pulse amplitude.
3 Measured at T1, R1 (V peak-to-zero, GND reference)
4 Transfer characteristics (1/4 input)
5 All measurements are with a matched-impedance transmit interface (see Figure 3. and Figure 4.) and with VDD or GND applied to
digital input leads.
Internal pull-up devices are provided on the following input leads: LP1, LP2, LP3 and ALMT. Internal pull-down devices are provided
on the following leads: SD, RBC, HDB3/TNDATA, TBC, SR/DR, FLM, and ZS. The internal pull-up or pull-down devices require the
input to source or sink to be no more than 20µA.

Stresses in excess of the Absolute Maximum Ratings can cause permanent damage to the device. These are absolute stress ratings
only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operation sec-
tions of the data sheet. Exposure to Absolute Maximum Ratings for extended periods can adversely affect device reliability.
