We call the TTL version "555" and the CMOS version "7555." This is called ELECTRONICS JARGON. The 555 comes as a single timer in an 8-pin package or a dual timer (556) in a 14 pin package. The 7555 comes as a single timer in an 8-pin package or a dual timer (7556) in a 14 pin package. The 555 and 7555 are called TIMERS or Timer Chips.
