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 VDD or GND.
5:
VDD = 3.3V for TC74X -3.3VCT. VDD = 5.0V for TC74X -5.0VCT. 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 VDD varies from
the nominal value, accuracy will degrade 1°C/V of VDD change.
