44 / 61 page  DSM2190F4 44/61 DC AND AC PARAMETERS This section summarizes the operating and mea- surement conditions, and the DC and AC charac- teristics of the device. The parameters in the DC and AC Characteristic tables that follow are de- rived from tests performed under the Measure- ment Conditions summarized in the relevant tables. Designers should check that the operating conditions in their circuit match the measurement conditions when relying on the quoted parame- ters. Table 22. Operating Conditions Table 23. AC Measurement Conditions Note: 1. Output Hi-Z is defined as the point where data out is no longer driven. Figure 26. AC Measurement I/O Waveform Figure 27. AC Measurement Load Circuit Table 24. Capacitance Note: 1. Sampled only, not 100% tested. 2. Typical values are for TA = 25°C and nominal supply voltages. Symbol Parameter Min. Max. Unit VCC Supply Voltage 3.0 3.6 V TA Ambient Operating Temperature (industrial) –40 85 °C Symbol Parameter Min. Max.
