I have a diagram of this chip, at pin 22 it has a G with a line above it. Is this a ground ? The reason I ask is because I have a socketed SMEC that doesn't work and would like to find out why. Thanks for any info.

Thanks for the link, shows pin 14 is the gnd. The NTE printout I have says Vss for that pin, is that some other langage for ground ?
