General Description
These Clock Generationand Support clock driversare spe-
cifically designedfor driving memory arrays requiring large
fanouts while operatingat high speeds.
This device meetstheriseandfall time requirementsoftheand100 MHz PentiumTM processors.
The CGS2535isa non-inverting4to16 driver with CMOS
I/O structures.The CGS2535specification guarantees part-
to-part skew variation.
Features Guaranteed:1.0ns rise andfall times while driving12 inchesof
50X microstrip terminated with25pF350ps pin-to-pin skew (tOSLHand tOSHL) 650ps part-to-part variationon positiveor negative
transition Operates with either 3.3Vor 5.0V supply Inputs5V tolerant with VCCin 3.3V range Symmetric output current drive:24mA IOH/IOL Industrial temperature range b40§Cto a85§C Symmetric package orientation Large fanoutfor memory driving applications Guaranteed2kV ESD protection Implementedon National’s ABT family process 28-pin PLCCfor optimum skew performance
