L64733 Signal Descriptions

This section describes the L64733 signals. Figure 5 shows the interface

diagram of the L64733. Names of signals that are active-LOW are

designated with an “n” sufﬁx (for example, ERROROUTn). Names of

differential signals are designated with a “p” sufﬁx for the noninverting

side (for example, QOUTp), and with an “n” sufﬁx for the inverting side

(for example, QOUTn).
