philips semiconductors product data ne590 addressable peripheral driver 2 2001 aug 03 853-0951 26836 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. features ? 8 high current outputs ? low-loading bus compatible inputs ? power-on clear ensures safe operation ? ne590 will operate in addressable or demultiplex mode ? allows random (addressed) data entry ? easily expandable ? ne590 is pin compatible with 54/74ls259 applications ? relay driver ? indicator lamp driver ? triac trigger ? led display digit driver ? stepper motor driver pin configurations n package ne590 1 2 3 4 5 6 7 8 9 10 11 12 13 14 16 15 top view a 0 a 1 a 2 q 0 q 1 q 2 q 3 gnd v cc clr ce d q 7 q 6 q 5 q 4 sl00479 figure 1. pin configuration pin description pin symbol name & function 1-3 a 0 -a 2 a 3-bit binary address on these pins defines which of the 8 output latches is to receive the data. 4-7, 9-12 q 0 -q 7 the 8 device outputs. the ne590 has open-collector darlington outputs. 13 d the data input. when the chip is enabled, this data bit is transferred to the defined output such that: a1o turns output switch aono a0o turns output switch aoffo 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. 15 clr the clear input. when clr goes low all output switches are turned aoffo. a high data input will override the clear function on the addressed latch. ordering information description temperature range order code dwg # 16-pin plastic dual in-line package (dip) 0 c to +70 c ne590n sot38-4
