TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TC75W56FU, TC75W56FK

Dual Comparator

TC75W56 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 push-pull output can connect

directly to local IC’s such as TTL and CMOS circuits.

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.
