= Side driving internal IC
= Side driving external cable (bidirectional)
= Side receiving control signals from internal cable
= Side driving external cable (unidirectional)
= Don’t care – control signals in
= High Z or 3-State
= Totem pole output
= Resistive pull up: 1.4k (nominal) on B/Y/C cable side and
V
Low signal on the A side, that particular B/Y side resistor is
switched out to stop current drain from V
When DIR = L and OEA = H, the output signal is isolated
from the input signal. B1 – 8 signals maintain an r
on the input for this mode.
