General Description
These Clock Generationand Support clock driversare spe-
cifically designedfor driving memory arrays requiring large
fanouts while operatingat high speeds,
CGS2534 isa4to16 inverting driver with TTL compatible
I/Os. This devicehas skew specificationsof 350ps pin-to-
pinas wellasa650ps specificationfor part-to-part propa-
gation delay variation.
Features Guaranteedand tested:
350ps pin-to-pin skew (tOSHLand tOSLH) 650ps part-to-part variationon positiveor negative
transition Implementedon National’s ABT family process Symmetric output current drive: b36/36mA IOH/IOL Industrial temperatureof b40§Cto a85§C 28-pin PLCCfor optimum skew performance Symmetric package orientation Large fanoutfor memory driving applications Guaranteed2kV ESD protection
