Functional Description
(Continued)
h.
An on-chip depletion load device to V
CC
.
i.
A Hi-Z input which must be driven to a ‘‘1’’ or ‘‘0’’ by
external components.
The above input and output configurations share common
enhancement-mode and depletion-mode devices. Specifi-
cally, all configurations use one or more of six devices
(numbered 1–6, respectively). Minimum and maximum cur-
rent (I
OUT
and V
OUT
) curves are given in Figure 8 for each
of these devices to allow the designer to effectively use
these I/O configurations in designing a COP410L/411L sys-
tem.
The SO, SK outputs can be configured as shown in
a., b.,
or
c.
The D and G outputs can be configured as shown in
a.
or
b.
Note that when inputting data to the G ports, the G out-
puts should be set to ‘‘1’’. The L outputs can be configured
as in
d., e., f.,
or
g.
An important point to remember if using configuration
d.
or
f.
with the L drivers is that even when the L drivers are
disabled, the depletion load device will source a small
amount of current. (SeeFigure 8, device 2.) However, when
the L port is used as input, the disabled depletion device
CANNOT be relied on to source sufficient current to pull an
input to a logic ‘‘1’’.
COP411L
If the COP410L is bonded as a 20-pin device, it becomes
the COP411L, illustrated in Figure 2, COP410L/411L Con-
nection Diagrams. Note that the COP411L does not contain
D2, D3, G3, or CKO. Use of this option of course precludes
use of D2, D3, G3, and CKO options. All other options are
available for the COP411L.
