Philips Semiconductors Linear Products Product specification 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.

SYMBOL NAME & FUNCTION 1-3 2-4 A0-A2 A 3-bit binary address on these pins defines which of the 8 output latches is to receive the data. 4-7, 9-12 5-8, 11-14 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. 14 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. - 1 CS The chip select input provides for an additional level of address decoding. - 10 VS 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.

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 August 31, 1994 523 Philips Semiconductors Linear Products Product specification Addressable peripheral drivers NE590/591 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.
