All measurements are with a matched-impedance transmit interface (see Figure 3. and Figure 4.) and with V
DD
or GND applied to
digital input leads.
Internal pull-up devices are provided on the following nput eads: 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 20
μ
A.
