NJM2207

The NJM2207 is video signal superimposer, with synchronous separation circuit, vertical sinchronous reproduce circuit and two video high performance switches for switching from video signal to character signal and backgroud signal.The NJM2207 is suitable for simply indicating the date time, TV channel and others.

Features of the NJM2207 are:(1)operating voltage: (+4.75V-v+13V); (2)with synchronous separation circuit; (3)with vertical sinchronous reproduce circuit; (4)package outline:DIP-14, DMP-14, ZIP-16; (5)bipolar technology.Usual TV has video (composite) signal output and input terminals to connect VCR or others.There is all information about picture on video composite signal (Ref, to Fig. 2).Its time signal of horizontal and vertical synchronous signal indicates the brighten place of TV tube. For brightening TV tube regardless video signal, the video input signal has to be switched to DC level(luminance level) on that scanning time. On this method, character is shown with background of usual picture.

The absolute maximum ratings of the NJM2207 can be summarized as:(1)supply voltage:17V;(2)storage temperature:-40 to +125;(3)operating temperature:-20 to 75 ;(4)power dissipation:DIP-14,300mW, DMP-14,400mW, ZIP-16,500mW.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
