TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TC75S57F, TC75S57FU, TC75S57FE

Single Comparator

The TC75S57F/TC75S57FU/TC75S57FE is a CMOS general-

purpose single comparator. The device can operate off a single

power supply and draws a lower supply current than a

conventional bipolar general-purpose comparator. This device’s

push-pull output stage can be directly connected to TTL or CMOS

logic ICs, among others.

Features

• Low-current power supply : I

DD

= 100 μA (typ.)

• Single power supply operation

• Wide common mode input voltage range : V

SS

to V

DD

− 0.9 V

• Push-pull output circuit

• Low input bias current

• Small package

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: This device’s CMOS structure makes it prone to latch-up. To prevent latch-up, please take the following

precautions:

• Ensure that no I/O pin’s voltage level ever exceeds V

DD

or drops below V

SS

.

In addition, check the power-on timing.

• Do not subject the device to excessive noise.
