CGS2535V
CGS2535V is Commercial Quad 1 to 4 Clock Drivers/Industrial Quad 1 to 4 Clock Drivers manufactured by 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
