The TPS841(F) and TPS843(F) represent a Si photo
IC of digital output type that integrates a photodiode,
amplifier circuit, and Schmitt trigger circuit into a
single chip.
These devices are low voltage drive types, and they
allow construction of low voltage systems which thus
consume less power.
These devices respond faster than the
phototransistor type. They output a high when light is
input.

(Note 1)
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).
