[sdiy] What does CAB mean when buying transistor arrays etc?

[Brett Maddaford]

I've often seen cab1 and cab5 etc beside descriptions of parts, ok silly
question probably for some but I have no idea what it means. Have
searched electronics terminology sites etc but am not finding much :(

for example I'm looking at the same part in an 8pin DIP and one is
marked as Cab9, cab10 and lin box....whats the difference?
