18、 INTRODUCTION The dimensions of integrated circuit devices are continuing to be reduced, both vertically and horizontally, to obtain better performance and higher density. However, if the supply voltages and interface levels are not reduced, the electric fields within the die (chip) will increase, w
19、hich leads to reduced reliability. These increased fields will also, together with the higher system-clock rate, lead to increased electromagnetic interference and noise induced on the supply leads and the ground plane, which leads to lower noise immunity and a higher probability of malfunction. To
20、continue this trend of scaling down the size of semiconductor devices, lower power supply voltages are essential. For systems operating at lower supply voltage, the tolerances on the supply voltage and the input and output voltages must be specified more closely. Also, since the market for battery-o
21、perated equipment is expected to grow considerably, it is important to include specifications that cover this field. By setting standard values at this stage, manufacturing costs can be reduced and users can design systems more economically. After the publication of first edition of this standard, s
22、caling of digital ICs has still been drastically proceeding, and nowadays, state-of-the art digital ICs are operated at 1,2 V, and Schmitt trigger interface is widely used. In light of the situation, this second edition expands the specification of nominal power supply voltage down to 1,0 V and incl
