Design Recommendations
1.5V to 3.3V I
To program the SiI 1162 via I
1.5V. To ensure proper initialization of the SiI 1162 a bi-directional voltage level-shifting circuit between the
SiI 1162 I
channel transistor like Fairchild Semiconductor’s NDC7002N or the Philips GTL2010 High Speed Bus Switch.
Refer to Figure 15 for a schematic example using a dual N-channel transistor for translating an I
3.3V I
Figure 16 illustrates a schematic example using the Philips GTL 2010 to achieve a 1.5V to 3.3V and 5V bi-
directional level-shift.
