TC77
2.0 TYPICAL PERFORMANCE CURVES
Note:
The graphs and tables provided following this note are a statistical summary based on a limited number of
samples and are provided for informational purposes only. The performance characteristics listed herein
are not tested or guaranteed. In some graphs or tables, the data presented may be outside the specified
operating range (e.g., outside specified power supply range) and therefore outside the warranted range.
Note: Unless otherwise indicated, all parameters apply at VDD = 3.3V for the TC77-3.3MXX and VDD = 5.0V for the TC77-
5.0MXX, and TA = -55°C to +125°C. The TC77-3.3MXX and TC77-5.0MXX will operate from a supply voltage of 2.7V
to 5.5V. However, the temperature accuracy of the TC77-3.3MXX and TC77-5.0MXX is specified at the nominal oper-
ating voltages of 3.3V and 5.0V, respectively.
