The TMS3471C is a monolithic integrated circuit designed to supply timing signals for the Texas Instruments (TI^TM) 11-mm diagonal TC241 monochrome CCD image sensor. The TMS3471C supplies both CCD drive signals and NTSC television synchronization signals at standard video rates. It requires a single 5-V supply voltage and a 14.318-MHz crystal-oscillator input. The TMS3471C provides several options, including multiple antiblooming modes, clamp-pulse selection, and delayed horizontal transfer.

The TMS3471C is used in conjunction with level-shifting devices such as the TI TMS3473B parallel driver and the TI TMS3472A serial driver. It also supplies sample-and-hold signals for the TI TL1593 three-channel sample-and-hold and multiplex signals for the TI TL1051 video preprocessor. The TMS3471C NTSC synchronization-signal outputs include composite sync, composite blank, clamp, subcarrier, subcarrier delayed by 90 degrees, and burst flag.

The TMS3471C is supplied in a 44-pin plastic flat package and is characterized for operation from 20°C to 45°C.
