A = Side driving internal IC
B = Side driving external cable (bidirectional)
C = Side receiving control signals from internal cable
Y = Side driving external cable (unidirectional)
X = Don’t care – control signals in
Z = High Z or 3-State
O.C.= Open collector
t_P = Totem pole output
r_P = Resistive pull up: 1.4kΩ (nominal) on B/Y/C cable side and
V_CC. However, while a B/Y side output is Low as driven by a
Low signal on the A side, that particular B/Y side resistor is
switched out to stop current drain from V_CC through it.
*
When DIR = L and OEA = H, the output signal is isolated
from the input signal. B1 – 8 signals maintain an r_P = 1.4kΩ
on the input for this mode.
