TYPICAL PERFORMANCE CURVES
Note: Unless otherwise indicated, all parameters apply at V
DD
= 3.3V for the TC77-3.3MXX and V
DD
= 5.0V for the TC77-
5.0MXX, and T
A
= -55癈 to +125癈. 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.
