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 1: Measurements for the TPS830(F) are based on a standard circuit which includes a 1000−pF capacitor
between VO and GND to prevent oscillation.
Note 2: Standard transmitter
In the figure above, the transmitter output VOUT is 80m Vpp.
The TPS703(F) in this application has a short−circuit current of Isc = 1.24μA when measured at E =
0.1mW/cm2. (E is the radiant incidence when a CIE standard light source A is used.)

Note 3: Transmission range L
Standard transmitter (TLN105B(F))
L
L is the maximum distance at which burst waves can be received from the transmitter unit, and at which
data can be processed by the receiver unit.
Note that when signals other than the recommended burst wave are transmitted, the transmission range
may be reduced or a malfunction may occur.
(*) The TLN105B(F) is used as the standard LED transmitter.
If the TLN231(F) is used instead, the transmission range is 1.2 times that of the TLN105B(F).
Example: 6m (with TLN105B(F)) ⇒ 10.1m (with TLN231(F))

Bit Pattern Designing Example (reference)
•
Example of code signal = 11010010
Sequence of LED signals = 1 must be avoided. If LED signals of 1
sequence, TPS830(F) may not receive LED signals properly. After an LED
signal of 1, 0 must be sent (55μ or longer interval necessary).
Please take this into account when designing a bit pattern.
The following shows the bit pattern t example that is converted at first
code signals to LED signals as shown on the right diagram.

6.
To stabilize the power line, insert a bypass capacitor of up to 0.01μF between VCC and GND, close to the
device.
At power−on the internal circuit takes about 100μs to stabilize. During this period the output signal is unstable
and may change.
To avoid unnecessary oscillation, insert a bypass capacitor of 1000pF between VCC and GND.
When using the device, please take the device’s characteristics, the operating environment and the
characteristics of pairing LED device into considerations.
Soldering temperature: ≦ 260°C, soldering time : ≦ 5s (Soldering must be performed under the 2mm from
the body of the device.)
When forming the leads, bend each lead under the 2mm from the body of the device. Soldering must be
performed after the leads have been formed.
