1.8 Choice of Voltage Specifications
To obtain better performance and higher density, semiconductor technologies are reducing the vertical and
horizontal dimensions of integrated device structures. Due to a number of electrical limitations in the
manufacture of VLSI devices and the need for low-voltage operation in memory cards, the JEDEC
committee decided to establish interface standards for devices operating at 3.3 V
±
0.3 V. To this end,
Hitachi guarantees all of its devices operational at 3.3 V
±
0.3 V. Note also that AC and DC specifications
are guaranteed between 3.0 and 5.5 V. Operation of FACT logic is also guaranteed from 2.0 to 6.0 V on
V
CC
.

HC = 2.0 to 6.0 V
1.9 FACT Replaces LS, ALS, HCMOS
The Advanced CMOS family is specifically designed to outperform the LS, ALS, and HCMOS families.
Figure 8 shows the relative position of various logic families in speed/power performance.
Table 1 summarizes the key performance specifications for various competitive technology logic families.
Table 2 compares propagation delays.
