TOSHIBA TB1240N TENTATIVE TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC TB1240N PAL/NTSC 1CHIP (IF + VCD PROCESSOR) IC TB1240N is the IF & Video processing IC for PAL/NTSC color TV system. This IC demodulates PAL/NTSC PIF, SIF and composite video signal to R/G/B primary colors and Audio signals. This IC can constitute Multi-Color System by combined with TA1275AZ (SECAM Processor). TB1240N has the analog R/G/B interface, therefore it is easy to make up PIP system by using this IC. TB1240N has an IC BUS interface. Various controls (Brightness, Color etc.) can be done via two bus lines. SDIP56-P-600-1.78 FEATURES Weight : 5.55g (Typ.)

This IC is not proof enough against a strong E-M field by CRT which may cause function errors and/or poor characteristics. Keeping the distance from CRT tothe IC longer than 20cm, or if cannot, placing shield metal over the IC, is recommended in an application.
