2.4

Electrical Specifications

TA = -40°C to +85°C. Typical values are at TA = +25°C, unless otherwise specified. A 0.01F bypass capacitor

between VDD and GND is used to minimize power supply noise.

2.4.1

Common Specifications

VDD = 1.8V ± 5%, 2.5V ± 5%,3.3V ± 5%, TA = -40°C to +85°C.

Figure 4. AC/DC Test Circuit

The AC and DC parameters are tested with Thevenin-equivalent circuits that make the most use of the 50ohm

terminations built into the scope. See Table 5 for details.
