CGS2535TV Datasheet | National Semiconductor

Description These Clock Generation and Support clock drivers are specifically designed for driving memory arrays requiring large fanouts while operating at high speeds. The CGS2535 is a non-inverting 4 to 16 driver with CMOS I/O structures. The CGS2535 specification guarantees partto-part skew variation. Features n Guaranteed: - 1.0 ns rise and fall times while driving 12 inches of 50Ω microstrip terminated with 25 p F - 350 ps pin-to-pin skew (t OSLH and t OSHL) n 650 ps part-to-part variation on positive or negative transition @ 5V VCC n Operates with either 3.3V or 5.0V supply n Inputs 5V tolerant with VCC in 3.3V range n Symmetric output current drive: 24 m A IOH/IOL n Industrial temperature range - 40˚C to +85˚C n Symmetric package orientation n Large fanout for memory driving applications n Guaranteed 2 k V ESD protection n Implemented on National’s ABT family process n 28-pin PLCC for optimum skew performance Ordering Information Order Number Package Number Package Description CGS2535V V28A 28-Lead Molded Plastic Leaded Chip Carrier Device also available in Tape and Reel.
