DESCRIPTION:

speedmicroprocessors.
DataisstoredintheinternalB-portregistersonthelow-to-hightransitionof
theclock(CLK)inputwhentheappropriateclock-enable(CLKENA)inputsare
low. Proper control of these inputs allows two sequential 12-bit words to be
presentedasa24-bitwordontheB-port.FordatatransferintheB-to-Adirection,
asinglestorageregisterisprovided.TheselectSELlineselects1Bor2Bdata

control terminals are registered so that all transactions are synchronous with
CLK.Dataflowiscontrolledbytheactive-lowoutputenables(OEA,OEB1and
OEB2).
The ALVCH16269 has been designed with a ±24mA output driver. This
driveriscapableofdrivingamoderatetoheavyloadwhilemaintainingspeed
performance.
TheALVCH16269has“bus-hold”whichretainstheinputs’laststatewhen-
ever the input goes to a high impedance. This prevents floating inputs and
eliminatestheneedforpull-up/downresistors.
