DESCRIPTION/ORDERINGINFORMATION
Thisoctalbuffer/linedriver isdesignedfor1.65-Vto3.6-VVCCoperation.
TheSN74ALVCH244isorganizedastwo4-bit linedriverswithseparateoutput-enable(OE) inputs.WhenOEis low, thedevicepassesdata fromtheA inputs to theYoutputs.WhenOE ishigh, theoutputsare in the high-impedancestate.
Toensurethehigh-impedancestateduringpoweruporpowerdown,OEshouldbetiedtoVCCthroughapullup resistor; theminimumvalueof theresistor isdeterminedbythecurrent-sinkingcapabilityof thedriver.
