description

These quadruple differential comparators are
fabricated using LinCMOS technology and
consist of four independent voltage comparators
designed to operate from a single power supply.
Operation from dual supplies is also possible if the
difference between the two supplies is 2 V to 18 V .
Each device features extremely high input
impedance (typically greater than 10

12

Ω),
allowing direct interfacing with high-impedance
sources. The outputs are n-channel open-drain
configurations and can be connected to achieve
positive-logic wired-AND relationships.

The TLC374 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 1000-V
ESD rating using human body model testing. However, care should be exercised in handling this device as
exposure to ESD may result in degradation of the device parametric performance.

The TLC374C is characterized for operation from 0°C to 70°C. The TLC374I is characterized for operation from
–40° to 85°C. The TLC374M is characterized for operation over full military temperature range of
–55°C to 125°C. The TLC374Q is characterized for operation from –40°C to 125°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values except differential voltages are with respect to network ground.

2. Differential voltages are at IN+ with respect to IN –.

3. Short circuits from outputs to VDD can cause excessive heating and eventual device destruction.

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 VDD. They can

be verified by applying the limit value to the input and checking for the appropriate output state.
