purposes. Linear RGB signals can be inserted from an
external source. RGB output signals are available for
driving the video output stages.

Notes
1. Maximum value 110 mA after warm-up.
2. Values are proportional to the supply voltage.
3. Matrixed according to equation V(GY) =0.51V(RY) 0.19V(BY).
4. Clipping due to internal signal limitation may occur when the Y input is greater than nominal and maximum contrast
and minimum brightness.
5. When V7-18 < 0.4 V during clamping time, the black levels of the inserted RGB signals are clamped on the black
levels of the internal RGB signals.
When V7-18 > 0.9 V during clamping time, the black levels of the inserted RGB signals are clamped on an internal
DC voltage (correct clamping of the external RGB signals is possible only when they are synchronous with the
sandcastle pulse).
6. Internal signal limitation is allowed to start at 5.5 V after warm-up time.
7. The sandcastle pulse is compared with three internal thresholds (proportional to VP) and the given levels separate
the various pulses.
8. Blanked to ultra-black (25%).
9. Pulse duration 3.5 µs.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
“IC Package Databook”
(order code 9398 652 90011).
Soldering by dipping or by wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
