... Column Address Strobe (CAS). RAS is used to latch the first eight bits and CAS is used to latch the latter eight bits. The IC41C1665 and the IC41LV1665 have two CAS controls, LCAS and UCAS. The LCAS and UCAS inputs internally generate a CAS signal functioning in an identical manner to the single CAS input on the other 64K x 16 DRAMs ...
