All characteristics are measured with zero common-mode input voltage unless otherwise noted. Full range is 0°C to 70°C for TLC372C, –40°C to 85°C for TLC372I, and –55°C to
125°C for TLC372M and –40°C to 125°C for TLC372Q. IMPORTANT: See Parameter Measurement Information.
NOTE 4: The offset voltage limits given are the maximum values required to drive the output above 4 V or below 400 mV with a 10-kΩ resistor between the output and V
DD
. They can
be verified by applying the limit value to the input and checking for the appropriate output state.
