Logic Control Outputs SD0-5
These outputs are directly controlled by the logic states of bits 0-5 in Register B. A logic low (GNDD) in Register B
causes the SD outputs to assume an inactive state. A logic high (V
DD
) in Register B causes the SD outputs to
assume an active state (see Table 3). SD0-2
switch between GNDD and V
DD
and may be used to control
external logic or transistor circuitry, for example, that employed on the line card for performing such functions
as relay drive for application of ringing to line, message waiting indication, etc.
SD3-5
are used primarily to drive external analog circuitry. Examples may include the switching in or out of gain
sections or filter sections (e.g., ring trip filter) (Figure 7).
MT8962/63/66/67 provides all six SD outputs.
MT8960/61/64/65 each packaged in an 18-pin DIP provide only four control outputs, SD0-3.
