IEC 60748-2-20:2008 aims at giving DC interface specifications for various sets of values, where each comprises the nominal value of power supply voltage, its tolerance, and the worst-case limit values of the input and output voltages for low voltage integrated circuits. This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
- Expansion of power supply voltages down to nominal 1,0 V
- Addition of Schmitt-trigger input specification.
