The pin numbers mentioned in the rest of this document are referenced to the SDIP56 (SOT400) package.
In the TDA 8840/41/42/46/46A the following pins are different:
Pin 16 (SECAM PLL decoupling): Not connected in the TDA 8840/41/46/46A
Pin 27: Not connected in TDA 8840/41/42
Pin 28: Luminance output in TDA 8840/41/42
Pin 29-32 (U/V interface): Not available in TDA 8840/41/42
Pin 35 (4.43 MHz X-tal): Not connected in the TDA 8846/46A
Pin 45 (E-W drive output): AVL capacitor
In the TDA 8857H the pins 28 (SECAM PLL decoupling) and 51 (4.43 MHz X-tal) are not connected.
