tsz22111 ? 15 ? 001 &&' /# <b( ! a!@#* i nput pins of an ic are often connected to the gate o f a mos transistor. the gate has extremely high impe dance and extremely low capacitance. if left unconnected, the electric field from the outside can easily charge it. the small charge acquired in this way is enough to produce a sig nificant effect on the conduction through the transi stor and cause unexpected operation of the ic. so unless othe rwise specified, unused input pins should be connect ed to the power supply or ground line. "! "@#* 2@ this monolithic ic contains p+ isolation and p subs trate layers between adjacent elements in order to keep them isolated. pn junctions are formed at the intersectio n of the p layers with the n layers of other elements, creating a parasitic diode or transistor. for example (refer to fig ure below): when gnd > pin a and gnd > pin b, the pn junction operates as a parasitic diode. when gnd > pin b, the pn junction operates as a para sitic transistor. parasitic diodes inevitably occur in the structure of the ic. the operation of parasitic diodes can result in mutual interference among circuits, operational faults, or ph ysical damage. therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the gn d voltage to an input pin (and thus to the p substrat e) should be avoided. figure 24. example of monolithic ic structure > % (#( when using a ceramic capacitor, determine the dielect ric constant considering the change of capacitance w ith temperature and the decrease in nominal capacitance d ue to dc bias and others. %!$ ( 9; this ic has a builtin thermal shutdown circuit that p revents heat damage to the ic. normal operation shoul d always be within the ics power dissipation rating. if howev er the rating is exceeded for a continued period, the j unction temperature (tj) will rise which will activate the tsd circuit that will turn off all output pins. when the tj falls below the tsd threshold, the circuits are automatically rest ored to normal operation. note that the tsd circuit operates in a situation th at exceeds the absolute maximum ratings and therefore, under no circumstances, should the tsd circuit be used in a se t design or for any purpose other than protecting the ic from heat damage. downloaded from: http:///
