Addressable peripheral drivers
NE590/591
DESCRIPTION
PIN CONFIGURATIONS
The NE590/591 addressable peripheral drivers are high current
latched drivers, similar in function to the 9334 address decoder. The
device has eight Darlington power outputs, each capable of 250mA
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.
N Package
The NE590 has eight open-collector Darlington outputs which sink
current to ground. The device is packaged in a 16-pin plastic or
Cerdip package.

The NE591 has eight open-emitter Darlington outputs which source
current to an external load from a common collector line, VS. This
VS line need not necessarily be the same as the 5V VCC supply. The
device is packaged in an 18-pin plastic or Cerdip package.

Q0-Q7
The 8 device outputs. The NE590 has open-collector Darlington outputs. The NE591 has open emitter-follower outputs.
13
15
D
The data input. When the chip is enabled, this data bit is transferred to the defined output such that:
“1” turns output switch “ON”
“0” turns output switch “OFF”
Thus in logic terms, the NE590 inverts data to the relevant output. The NE591 retains true data at the
output.

16
CE
The chip enable. When this input is low, the output latches will accept data. When CE goes high, all
outputs will retain their existing state regardless of address or data input conditions.
15
17
CLR
The clear input. When CLR goes low all output switches are turned “OFF”. On the NE590, a high
data input will override the clear function on the addressed latch. On the NE591, CLR low will override any other condition.

The VS line provides the power to all 8 output devices. It is connected to the collectors of all 8 output
transistors. This pin may be connected to the VCC or another supply.

dissipation is limited by the package to 1W, and since the power
dissipation due to supply current is 0.25W, the total load power
dissipation by the device is limited to 0.75W, and decreases as
ambient temperature rises.
FUNCTIONAL DESCRIPTION
These peripheral drivers have latched outputs which hold the input
data until cleared. The NE590 has active-Low, open-collector
outputs, while the NE591 has active-High, uncommitted (open)
emitter outputs. All outputs are cleared when power is first applied.
The maximum die junction temperature must be limited to 165°C,
and the temperature rise above ambient and the junction
temperature are defined as:
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 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. For NE591, CS must be brought Low
any time CE is Low if any outputs are to be changed.
tR=θJA×P
tJ=tA+tR
where
θJA is die junction to ambient thermal resistance.
PD is total power dissipation
tR is junction temperature rise above ambient
tj is die junction temperature
tA is ambient (surrounding medium) temperature
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. For the
NE591, the CS input must also be Low.
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 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 250mW 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:
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 and NE591 are capable of output currents of 250mA at each
of their eight outputs. It should be noted, however, that the load
power dissipation would be over 2.5W if all 8 outputs were to carry
their full rated load current at one time. Since the total power

Plastic tR=83×0.7235=60°C
Plastic tJ=50+60=100°C
Cerdip tR=100×0.7235=72.40°C
Cerdip tJ=50+72.4=122.4°C
Thus we find that tJ 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.
