I have a rotation sensor from a 1999 Solectria Force electric car that uses optical sensors to detect silver and black segments on a spinning disk. My question is about a TLC 274 Quad Op Amp on the board thqt appears to not be working correctly (with a supply of 6V the output will only go up to about 2.4V.) Standard pinout for the TLC274 has outputs on pins 1, 7, 8, and 14, but looking at the board it makes no sense whatsoever unless the outputs were on pins 2, 6, 9, and 13. Were any made with nonstandard pinouts? Is there a source for these or a replacement anywhere to be had?
