UPD3794CY

The UPD3794CY is designed as one kind of 2700 PIXELS x 3 color CCD linear image sensor which changes optical images to electrical signal and has the function of color separation.It has 3 rows of 2700 pixels, and each row has a single-sided readout type of charge transfer register.And it has reset feed-through level clamp circuits, a clamp pulse generation circuit, an RGB selector and voltage amplifiers. Therefore, it is suitable for 300 dpi/A4 color image scanners, color facsimiles and so on.

Features of the UPD3794CY are:(1)valid photocell:2700 pixels x 3;(2)photocell's pitch:8 um;(3)line spacing:32 mm (4 lines) green line-blue line, blue line-red line;(4)color filter:primary colors (red, green and blue), pigment filter (with light resistance 107 lx•hour);(5)resolution:12 dot/mm A4 (210 x 297 mm) size (shorter side) 300 dpi US letter (8.5" x 11") size (shorter side);(6)drive clock level:CMOS output under 5 V operation;(7)data rate:4 MHz max.;(8)power supply:+12 V;(9)on-chip circuits:reset feed-through level clamp circuits,clamp pulse generation circuit,RGB selector and voltage amplifiers.

The absolute maximum ratings of the UPD3794CY can be summarized as:(1)output drain voltage:-0.3 to +15 V;(2)shift register clock voltage:-0.3 to +8 V;(3)reset gate clock voltage:-0.3 to +8 V;(4)transfer gate clock voltage:-0.3 to +8 V;(5)RGB select input voltage:-0.3 to +8 V;(6)operating ambient temperatur-e:-25 to +60 °C;(7)storage temperature:-40 to +70 °C.If you want to know more information such as the electrical characteristics about it,please download the datasheet in www.seekic.com or www.chinaicmart.com .
