| INTEGRATED CIRCUITS DATA SHEET TDA4565 Colour transient improvement circuit Product specification File under Integrated Circuits, IC02 November 1989 Philips Semiconductors Product specification Colour transient improvement circuit GENERAL DESCRIPTION TDA4565 The TDA4565 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 730 ns to 1000 ns in steps of 90 ns and additional fine adjustment of 50 ns * Two Y output signals; one of 180 ns less delay QUICK REFERENCE DATA PARAMETER Supply voltage (pin 10) Supply current (pin 10) Y-signal delay at pin 12 V15-18 = 0 to 2.5 V V15-18 = 3.5 to 5.5 V V15-18 = 6.5 to 8.5 V V15-18 = 9.5 to 12 V Y-signal attenuation (R-Y) and (B-Y) signal attenuation output transient time Note 1. Delay time is proportional to resistor R14-18. R14-18 also influences the bandwidth; a value of 1.2 k results in a bandwidth of 5 MHz (typ.).

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. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
