DESCRIPTION
PIN CONFIGURATIONS
The NE590 addressable peripheral driver is a high current latched
driver, similar in function to the 9334 address decoder. The device
has eight Darlington power outputs, each capable of 250 mA load
current. The outputs are turned on or off by respectively loading a
logic HIGH or logic LOW 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. A common clear input, CLR, turns all outputs off
when a logic LOW is applied.

defined output such that:
APPLICATIONS
• Relay driver
“1” turns output switch “ON”
“0” turns output switch “OFF”
• Indicator lamp driver
• Triac trigger
Thus in logic terms, the NE590 inverts
data to the relevant output.
• LED display digit driver
• Stepper motor driver

the output latches will accept data. When
CE goes HIGH, all outputs will retain their

output switches are turned “OFF”.
A HIGH data input will override the clear

FUNCTIONAL DESCRIPTION
These peripheral drivers have latched outputs which hold the input
data until cleared. The NE590 has active-Low, open-collector
outputs. All outputs are cleared when power is first applied.

Addressable Latch Function
where
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 input, 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, CE, and “D” inputs Low.

is ambient (surrounding medium) temperature
For example, if we are using the NE590 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 10 mA, we find from the graph of
output voltage versus 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 0.4 V,
respectively. Total device power due to these loads is found to be
473.5 mW. Adding the 250 mW due to the power supply brings total
device power dissipation to 723.5 mW. The thermal resistance is
83 °C per W for plastic packages. Using the equations above we
find:
Demultiplexer Operation
By bringing the CLR and CE inputs Low and the “D” input High, the
addressed output will remain on and all other outputs will be off. This
condition will remain only as long as the output is addressed.
High Current Outputs
The obvious advantage of these devices over the 9334 and
N74LS259 (which provide a similar function) is the fact that the
NE590 is capable of output currents of 250 mA at each of its eight
outputs. It should be noted, however, that the load power dissipation
would be over 2.5 W if all 8 outputs were to carry their full rated load
current at one time. Since the total power dissipation is limited by
the package to 1 W, and since the power dissipation due to supply
current is 0.25 W, the total load power dissipation by the device is
limited to 0.75 W, and decreases as ambient temperature rises.
T
R
= 83 × 0.7235 = 60 °C
T = 50 + 60 = 100 °C
j
Thus we find that T is below the 165 °C maximum and this package
j
could be used in this application. The graphs of total load power
versus ambient temperature would also give us this same
information, although interpreting the graphs would not yield the
same accuracy.
