TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TC75W58FU, TC75W58FK

Dual Comparator

TC75W58 is a CMOS type general-purpose dual comparator capable

of single power supply operation and using lower supply currents

than the conventional bipolar comparators. Its open drain output

forms wired OR with other open drain outputs.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even

if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum

ratings and the operating ranges.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook

(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test

report and estimated failure rate, etc).

Note: Since this product sometimes brings about latchcap, which is peculiar to CMOS devices, note the following

points:

• Don’t raise the voltage level of I/O pins beyond V

DD

, nor lower it below V

SS

.

Consider the timing for power supply, too.

• Don’t let any abnormal noise enter the device.

Note: Since this product causes an increase in current consumption with a rise in operational frequency, make sure

that power consumption does not exceed the allowable dissipation.
