CGS2535V Commercial Quad 1 to 4 Clock Drivers/CGS2535TV Industrial Quad 1 to 4 Clock Drivers March 1997 CGS2535V/CGS2535TV Commercial Quad 1 to 4 Clock Drivers/Industrial Quad 1 to 4 Clock Drivers General Description These Clock Generation and Support clock drivers are specifically designed for driving memory arrays requiring large fanouts while operating at high speeds. This device 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. — 350 ps pin-to-pin skew (tOSLH and tOSHL) 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 mA 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 kV ESD protection n Implemented on National’s ABT family process n 28-pin PLCC for optimum skew performance Features n Guaranteed: — 1.0 ns rise and fall times while driving 12 inches of 50Ω microstrip terminated with 25 pF Connection Diagrams Pin Assignment for 28-Pin PLCC CGS2535 DS011954-2 DS011954-5 Truth Table Input In (0–3) Output ABCD Out (0–3) Pentium™ is a trademark of Intel Corporation. © 1997 National Semiconductor Corporation DS011954 http:\\www.national.com Absolute M...
