56 m pd78044h, 78045h, 78046h cautions on cmos devices 1 countermeasures against static electricity for all moss caution when handling mos devices, take care so that they are not electrostatically charged. strong static electricity may cause dielectric breakdown in gates. when transporting or storing mos devices, use conductive trays, magazine cases, shock absorbers, or metal cases that nec uses for packaging and shipping. be sure to ground mos devices during assembling. do not allow mos devices to stand on plastic plates or do not touch pins. also handle boards on which mos devices are mounted in the same way. 2 cmos-specific handling of unused input pins caution hold cmos devices at a fixed input level. unlike bipolar or nmos devices, if a cmos device is operated with no input, an intermediate- level input may be caused by noise. this allows current to flow in the cmos device, resulting in a malfunction. use a pull-up or pull-down resistor to hold a fixed input level. since unused pins may function as output pins at unexpected times, each unused pin should be separately connected to the v dd or gnd pin through a resistor. if handling of unused pins is documented, follow the instructions in the document. 3 statuses of all mos devices at initialization caution the initial status of a mos device is unpredictable when power is turned on. since characteristics of a mos device are determined by the amount of ions implanted in molecules, the initial status cannot be determined in the manufacture process. nec has no responsibility for the output statuses of pins, input and output settings, and the contents of registers at power on. however, nec assures operation after reset and items for mode setting if they are defined. when you turn on a device having a reset function, be sure to reset the device first. fip is a trademark of nec corporation. iebus is trademark of nec corporation. ms-dos and windows are trademarks of microsoft corporation. ibm dos, pc/at, and pc dos are trademarks of ibm corporation. hp9000 series 300, hp9000 series 700, and hp-ux are trademarks of hewlett-packard. sparcstation is a trademark of sparc international, inc. sunos is a trademark of sun microsystems, inc. news and news-os are trademarks of sony corporation.
