DESCRIPTION:

• 0.5 MICRON CMOS Technology

This 18-bit registered bus transceiver is built using advanced dual metal

CMOStechnology.Dataflowineachdirectioniscontrolledbyoutput-enable

(OEABandOEBA)andclock-enable(CLKENABandCLKENBA)inputs.For

theA-to-Bdataflow,thedataflowsthroughasingleregister.TheB-to-Adata

canflowthroughafour-stagepipelineregisterpath,orthroughasingleregister

path,dependingonthestateoftheselect(SEL)input.Dataisstoredintheinternal

registersonthelow-to-hightransitionoftheclock(CLK)input,providedthatthe

appropriateCLKENinputsarelow.TheA-to-Bdatatransferissynchronized

totheCLKABinput,andB-to-AdatatransferissynchronizedwiththeCLK1BA

andCLK2BAinputs.

• Typical tSK(o) (Output Skew) < 250ps

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

• VCC = 3.3V ± 0.3V, Normal Range

• VCC = 2.7V to 3.6V, Extended Range

• VCC = 2.5V ± 0.2V

• CMOS power levels (0.4µ W typ. static)

• Rail-to-Rail output swing for increased noise margin

• Available in SSOP, TSSOP, and TVSOP packages

DRIVE FEATURES:

• High Output Drivers: ±24mA (A port)

• Balanced Output Drivers: ±12mA (B port)

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
