DC CHARACTERISTICS (CONTINUED)

Electrical Specifications: Unless otherwise noted, VDD = 3.3V for TC74AX-3.3VXX and

VDD = 5.0V for TC74AX-5.0VXX, -40°C  TA  125°C. Note 5

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 VDD or GND.

5: VDD = 3.3V for TC74AX -3.3 VXX. VDD = 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 VDD varies from the nominal value, accuracy will degrade 1°C/V

of VDD change.
