All characteristics are measured with zero common-mode input voltage unless otherwise noted. Full range is 0°C to 70°C for TLC374C, –40°C to 85°C for TLC374I, and –55°C to
125°C for the TLC374M, and –40°C to 125°C for TLC374Q. MAX is 70°C for TLC374C, 85°C TLC374I, and 125°C for the TLC374M, and 125°C for TLC374Q. 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.
