Maximum rating
The maximum ratings are the limit values which must not be exceeded when using the device. Any
one of the rating must not be exceeded. If The maximum rating is exceeded, the characteristics may
not be recovered. In some extreme cases, the device may be permanently damage.
Soldering
Optical modules use semiconductor devices internally. However, in principle, optical modules are
optical components. At soldering, take care that flux dose not contact the emitting surface or
detecting surface. Also take care at flux removal after soldering.
Some optical modules come with protective cap. The protective cap is used to avoid malfunction when
the optical module is not in use. Not that it is not dust or waterproof.
As mentioned before, optical modules are optical component. Thus, in principle, soldering where there
may be flux residue or flux removal after soldering is not recommended. Toshiba recommends that
soldering be performed without the optical module mounted on the board. Then, after the board is
cleaned, solder the optical module manually. Do not perform any further cleaning.
If the optical module cannot be soldered manually, use non−halogen (chlorine−free) flux and make
sure, without cleaning, there is no residue such as chlorine. This is one of the ways to eliminate the
effects of flux. In such a case, check the reliability.
Noise resistance
Where the fiber optic receiving module case uses conductive resin, shield by connecting the
reinforcing pin at a front end of the module to GND. When using this optical module, connect the pin
to SIGNAL−GND.
Where the fiber optic receiving module case has a resistance of several tens of ohms, take care that
the case does not contact power line of other circuits.
It is believed that the use of optical transfer devices improve the noise resistance. In principle, optical
fiber is not affected by noise. However, especially receiving module which handle signals whose level
is extremely small, are comparatively more susceptible to noise.
TOSLINK improves noise resistance using a conductive case. However, the current of the signal
output from the photodiode of the optic receiving module is extremely small. Thus, depending on the
usage environment, shielding the case is not sufficient for noise resistance.
When using TOSLINK, Toshiba recommends that you test using the actual device and check the
noise resistance.
Use a simple noise filter on the TOSLINK fiber optic receiving module power line. If the ripple in
power supply used is high, further reinforce the filter.
When locating the optical module in an area susceptible to radiated noise, increase shielding by
covering the optical module and the power line filter using a metallic cover.
Vibration and shock
This module is resin−molded construction with wire fixed by resin. This structure is relatively sound
against vibration or shock, In actual equipment, there are some cases where vibration, shock, and
stress is applied to soldered parts or connected parts, resultingin line cut. Attention must be paid to
the design of the mechanism for applications which are subject to large amounts of vibration.

Fixing fiber optical receiving module
Solder the fixed pin (pins 5 and 6) of fiber optic receiving module TORX193K to the printed circuit
board to fix the module to the board.
Panel attachment
TORX193K provides hole for panel attachment. Please be sure to attach it to panel.
Shielding and wiring pattern of fiber optic receiving modules
To shield, connect the fixed pins (pins 5 and 6) of fiber optic transceiving module TORX193K to the
GND.
Where the fiber optic receiving module uses conductive resin, be careful that the case does not touch
wiring (including land).
To improve noise resistance, shield the optical module and the power line filter using a metallic cover.
Solvent
When using solvent for flux removal, do not use a high acid or high alkali solvent. Be careful not to
pour solvent in the optical connector ports. If solvent is inadvertently poured there, clean with cotton
tips.
Protective cap
When the fiber optic receiving module TORX193K is not in use, use the protective cap.
Supply voltage
Use the supply voltage within the Typ. operating condition (VCC = 5 ± 0.25 V). Make sure that supply
voltage does not exceed the maximum rating value of 7 V, even instantaneously.
Interface
TORX193K has a TTL interface. It can be interfaced with C−MOS IC that has compatibility with TTL
level.
Output
When the receiver output is at low level and connected to the power supply, or when the output is at
high level and connected to GND, the internal IC may be destroyed.
Soldering condition
Solder at 260°C or less within ten seconds.
Precaution on waste
When discarding devices and packing materials, follow procedures stipulated by local regulations in
order to protect the environment against contamination.
Precaution on use
Toshiba is continually working to improve the quality and the reliability of its products. Nevertheless,
