Description

These Clock Generation and Support clock drivers are specifically designed for driving memory arrays requiring large fanouts while operating at high speeds.

CGS2535V meets the rise and fall time requirements of the 90 and 100 MHz Pentium™ processors. The CGS2535 is a non-inverting 4 to 16 driver with CMOS I/O structures. The CGS2535 specification guarantees part-to-part skew variation.
