Conditions
Note 1: Operating current is an average value integrated over multiple conversion cycles. Transient current may
exceed this specification.
2: Maximum ensured conversion time after Power-on Reset (POR to DATA_RDY) is 250 msec.
3: Output current should be minimized for best temperature accuracy. Power dissipation within the TC74 will
cause self-heating and temperature drift error.
4: SDA and SCLK must be connected to V
DD
or GND.
5: V
DD
= 3.3V for TC74AX -3.3 VXX. V
DD
= 5.0V for TC74AX -5.0 VXX. All part types of the TC74 will operate
properly over the wider power supply range of 2.7V to 5.5V. Each part type is tested and specified for rated
accuracy at its nominal supply voltage. As V
DD
varies from the nominal value, accuracy will degrade 1癈/V
