TDA4566
GENERAL DESCRIPTION
The TDA4566 is a monolithic integrated circuit for colour-transient improvement (CTI) and luminance delay line in gyrator
technique in colour television receivers.
Features
• Colour transient improvement for colour difference signals (R-Y) and (B-Y) with transient detecting-, storage- and
switching stages resulting in high transients of colour difference output signals
• A luminance signal path (Y) which substitutes the conventional Y-delay coil with an integrated Y-delay line
• Switchable delay time from 550 ns to 820 ns in steps of 90 ns and additional fine adjustment of 37 ns
• Two Y output signals; one of 180 ns less delay

Notes
1. Output signal transient time measured with C6-18 = C9-18 = 220 pF without resistor (see Fig. 3).
2. Output current measured with emitter follower with constant current source of 0.6 mA.
3. R14-18 influences the bandwidth; a value of 1.2 kΩ results in a bandwidth of 5 MHz (typ.).
4. Delay time is proportional to resistor R14-18. Devices with suffix “A” require the value of the resistor to be 1.15 kΩ;
a 27 kΩ; resistor connected in parallel with R14-18 = 1.2 kΩ.;

time of successive solder waves must not exceed
5 seconds.
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.
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.
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).
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.
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
