DESCRIPTION
The NE/SA5090 addressable relay driver is a high-current latched
driver, similar in function to the 9934 address decoder. The device
has 8 open-collector Darlington power outputs, each capable of
150mA load current. The outputs are turned on or off by respectively
loading a logic "1" or logic "0" into the device data input. The
required output is defined by a 3-bit address. The device must be
enabled by a CE input line which also serves the function of further
address decoding. A common clear input, CLR, turns all outputs off
when a logic "0" is applied. The device is packaged in a 16-pin
plastic or Cerdip package.

FUNCTIONAL DESCRIPTION
This peripheral driver has latched outputs which hold the input date
until cleared. The NE5090 has active-Low, open-collector outputs,
all of which are cleared when power is first applied. This device is
identical to the NE590, except the outputs can withstand 28V.
Addressable Latch Function
Any given output can be turned on or off by presenting the address
of the output to be set or cleared to the three address pins, by
holding the "D" input High to turn on the selected output, or by
holding it Low to turn off, holding the CLR input High, and bringing
the CE input Low. Once an output is turned on or off, it will remain
so until addressed again, or until all outputs are cleared by bringing
the CLR input Low while holding the CE input High.
Demultiplexer Operation
By holding the CLR and CE inputs Low and the "D" input High, the
addressed output will remain on and all other outputs will be off.
High Current Outputs
The obvious advantage of this device over other drivers such as the
9334 and N74LS259 is the fact that the outputs of the NE5090 are
each capable of 200mA and 28V. It must be noted, however, that the
total power dissipation would be over 2.5W if all 8 outputs were on
together and carrying 200mA each. Since the total power dissipation
is limited by the package to 1W, and since power dissipation due to
supply current is 0.25W, the total load power dissipation by the
device is limited to 0.75W at room temperature, and decreases as
ambient temperature rises.
The maximum die junction temperature must be limited to 165
C,
and the temperature rise above ambient and the junction
temperature are defined as:
T
R
=
JA
P
D
T
J
=T
A
+t
R
where
For example, if we are using the NE5090 in a plastic package in an
application where the ambient temperature is never expected to rise
above 50
C, and the output current at the 8 outputs, when on, are
100, 40, 50, 200, 15, 30, 80, and 10mA, we find from the graph of
output voltage vs load current that the output voltages are expected
to be about 0.92, 0.75, 0.78, 1.04, 0.5, 0.7, 0.9, and 0.4V,
respectively. Total device power due to these loads is found to be
473.5mW. Adding the 200mW due to the power supply brings total
device power dissipation to 723.5mW. The thermal resistances are
83
C,per W for plastic packages and 100
C per W for Cerdips.
Using the equations above we find:
Plastic T
R
=83
0.7235=60
C
Plastic T
J
=50+60=100
C
Cerdip T
R
=100
0.7235=72.4
C
Cerdip T
J
=50+72.4=122.4
C
Thus we find that T
J
for either package is below the 165
C
maximum and either package could be used in this application. The
graphs of total load power vs ambient temperature would also give
us this same information, although interpreting the graphs would not
yield the same accuracy.
