Philips Semiconductors Linear Products Product specification Addressable relay driver NE/SA5090 DESCRIPTION PIN CONFIGURATION 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.

SYMBOL NAME AND FUNCTION 1-3 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 Q0-Q7 The 8 device outputs. 13 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” 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 of data input condition. 15 CLR The clear input. When CLR goes low all output switches are turned “OFF”. The high data input will override the clear function on the addressed latch.

The maximum die junction temperature must be limited to 165°C, and the temperature rise above ambient and the junction temperature are defined as: 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. TR=θJA×PD TJ =TA+tR 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 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. 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: 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 Plastic TR=83×0.7235=60°C Plastic TJ =50+60=100°C Cerdip TR=100×0.7235=72.4°C Cerdip TJ =50+72.4=122.4°C 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. August 31, 1994 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. 515 Philips Semiconductors Linear Products Product specification Addressable relay driver NE/SA5090 TIMING DIAGRAMS D D tPW tPW CE tPLH tPLH tPHL tPHL Q Q NOTE: Other Inputs: CLR = H, A = Stable NOTE: Other Inputs: CE = I, CLR = H, A = Stable Turn-On and Turn-Off Delays, Enable-to-Output and Enable Pulse Width Turn-On and Turn-Off Delays, Data-to-Output A CLR tPLH A tPHL Q tPLH Q NOTE: Other Inputs: CE = L, CLR = L, D = H ÉÉÉ ÉÉÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ ÉÉÉ Turn-On and Turn-Off Delays, Address-to-Output D tHH CE tSH Turn-Off Delays, Clear-to-Output ÉÉÉÉÉÉ ÉÉÉÉÉÉ ÉÉÉÉÉÉ ÉÉÉÉÉÉ tHL A tSL tS CE Q NOTE: Other Inputs: CLR = H, A = Stable NOTE: Other Inputs: CLR = H Setup and Hold Time, Data-to-Enable August 31, 1994 Setup Time, Address-to-Enable 516 Philips Semiconductors Linear Products Product specification Addressable relay driver NE/SA5090 TYPICAL APPLICATIONS + 5V +5V TO 28V RL DATA BUS µP 4 + 5V + 5V D D Q0 Q1 Q2 Q3 Q0 Q5 Q6 Q7 A2 A1 A0 5090 CE CLR IQ CONTROL A2 A1 A0 5090 CE CLR Q0 Q1 Q2 Q3 Q0 Q5 Q6 Q7 RELAY LOAD Driving Simple Loads +5V CLEAR +28V Q0 Q1 Q2 Q 5090 Q3 0 Q5 CE Q6 Q7 +5V +5V D A0 A1 A2 5090 3–BIT COUNTER 555 NOTE: A0, A1, A2 may be connected to the address bus if permitted by system design.
