The markings at the top say "TC104-1", and at the bottom "9041".

It was found in a box of random ICs and parts, and googling hasn't lead me anywhere.

  • \$\begingroup\$ Googling "TC104 ccd" brings up useful results. That would be hard to guess if one doesn't recognize that chip as a linear CCD sensor. \$\endgroup\$

  • \$\begingroup\$ The 9041 is probably a date code: 41st week of 1990. These sensor have been used in astronomy since the 1980s (at least). \$\endgroup\$

1 Answer 1


Looks to be a Texas Instrument TC 104-1, CCD line scan sensor.

From Data Sheet Archive I was able to find:


  • Linear CCD Image Array - DR 1000:1,WhiteRefer.Elements
  • Vertical Pixel Count=1
  • Horizontal Pixel Count=3456
  • Vertical Pixel Dimension (m)=10.7u
  • Horizontal Pixel Dimension (m)=10.7u
  • Horizontal Dimension (m)=36.9m
  • Vertical Dimension (m)=10.7u
  • Vsup Nom.(V) Supply Voltage=14
  • P(D) Max.(W) Power Dissipation=112m
  • Package=DIP

These types of chips are typically used for automated inspection cameras or flat bed scanners. They are a 1D CCD sensor.

  • \$\begingroup\$ I'm having a hard time finding the datasheet. \$\endgroup\$ Sep 9, 2012 at 1:40
  • \$\begingroup\$ These specs seem consistent with someone else looking for these back in 1995. \$\endgroup\$ Sep 9, 2012 at 2:00
  • \$\begingroup\$ I dont suppose anyone can find the datasheet could they? \$\endgroup\$
