TB1261F/TB1262F
TOSHIBA BiCMOS INTEGRATED CIRCUIT, SILICON MONOLITHIC
TB1261F/TB1262F
PAL/NTSC/SECAM 1CHIP
(IF + VCD PROCESSOR)
The TB1261F/TB1262F are TV signal processor ICs, which
contains PIF, SIF, Video, Chroma and Deflection blocks. They can
be applied for worldwide Multi system TV sets.
The flexibility of this TB1261F/TB1262F contributes to
reduce development costs and components in a TV set.

(*1) When using this device at above Ta=25℃, the power dissipation decreases by 15.9mV per 1℃ rise.
(*2) This IC is weak against static electricity and surge impulse. Please take counter measure to meet, if
necessary.
(*3) This IC is not proofed enough against a strong E-M field by CRT which mau cause function error
and/or poor characteristics. Keeping the distance from CRT to the IC longer than 20cm, or if cannot,
placing shield metal over the IC, is recommended in an application.
