NE590
DESCRIPTION
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. The NE590 has eight open-collector Darlington outputs which sink current to ground. The device is packaged in a 16-pin plastic DIP package.

PIN DESCRIPTION
PIN 1-3 SYMBOL A0-A2 NAME & FUNCTION A 3-bit binary address on these pins defines which of the 8 output latches is to receive the data. The 8 device outputs. The NE590 has open-collector Darlington outputs. 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. 14 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. The clear input. When CLR goes LOW all output switches are turned "OFF". A HIGH data input will override the clear function on the addressed latch.

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.
The maximum die junction temperature must be limited to 165 C, and the temperature rise above ambient and the junction temperature are defined as: TR = JA x P Tj = Tamb + TR where JA is die junction to ambient thermal resistance. PD is total power dissipation TR is junction temperature rise above ambient Tj is die junction temperature Tamb 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: TR = 83 x 0.7235 = 60 C Tj = 50 + 60 = 100 C Thus we find that Tj is below the 165 C maximum and this package 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.
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.
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.
