The TCA640 from NXP Semiconductors is an integrated chrominance amplifier suitable for SECAM decoders or double standard PAL/SECAM decoders. Standard switching is handled internally, controlled by an external DC signal.
Key features include a 7/8 kHz flip-flop, an identification circuit for SECAM, and a blanking circuit, burst gating circuit, and color killer detector. It operates with a nominal supply voltage of 12V and a typical supply current of 37mA. The device supports various input and output voltage levels for PAL and SECAM signals, with specified blanking and attenuation levels.
Packaged in a 16-lead DIL plastic package (SOT-38), the TCA640 is designed for through-hole mounting. Its operating temperature range is -25 to +125 °C, with a storage temperature range of -25 to +125 °C. The maximum power dissipation is 625 mW.
