〇 HEV (Hybrid Electric Vehicle)
and EV (Electric Vehicle) Applications
Unit: mm
The Toshiba TLX9376 consists of an infrared LED and integrated high gain,
high-speed photodetector. The TLX9376 is housed in the SO6 package. It
has a totem-pole output that can both sink and source current. The
photodetector has an internal Faraday shield that provides a guaranteed
common-mode transient immunity of 15 kV/μs. TLX9376 guarantees
minimum and maximum of propagation delay time, switching speed
dispersion, and high common mode transient immunity.

A ceramic capacitor (0.1 μF) should be connected
from pin 6 (VCC) to pin 4 (GND) to stabilize the
operation of the high gain linear amplifier. Failure to
provide the bypass may impair the switching
property. The total lead length between capacitor
and coupler should not exceed 1 cm.

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.
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 1: Pulse width ≤ 1 μs, 300 pps

of the high gain linear amplifier. Failure to provide the bypass may impair the switching property.
The total lead length between capacitor and coupler should not exceed 1 cm.
Note 1: CL is less than 15pF which includes probe and Jig/stray wiring capacitance.
Note 2: Propagation delay skew is defined as the difference between the largest and smallest propagation delay
times (i.e. tpHL or tpLH) of multiple samples. Evaluations of these samples are conducted under identical
test conditions (supply voltage, input current, temperature, etc).
Note 3: CMH is the maximum rate of rise of the common mode voltage that can be
sustained with the output voltage in the logic high state (VO > 4.0 V)
Note 4: CML is the maximum rate of fall of the common mode voltage that can be
sustained with the output voltage in the logic low state (VO < 0.4 V).
