EXCHANGER WITH 3-STATE
OUTPUTS AND BUS-HOLD
DESCRIPTION:
This 12-bit to 24-bit registered bus exchanger is used in applications in
which two separate ports must be multiplexed onto, or demultiplexed from,
asingleport.Itisparticularlysuitableasaninterfacebetweensynchronous
DRAMs and high-speed microprocessors.
DataisstoredintheinternalB-portregistersonthelow-to-hightransition
of the clock (CLK) input when the appropriate clock-enable (CLKENA)
inputs are low. Proper control of these inputs allows two sequential 12-bit
words to be presented as a 24-bit word on the B-port. For data transfer
intheB-to-Adirection,asinglestorageregisterisprovided.Theselect SEL
line selects 1B or 2B data for the A outputs. The register on the A output
permits the fastest possible data transfer, thus extending the period during
which the data is valid on the bus. The control terminals are registered so
that all transactions are synchronous with CLK. Data flow is controlled by
the active-low output enables (OEA, OEB1 and OEB2).
The ALVCHR162269A has series resistors in the device output struc-
ture which will significantly reduce line noise when used with light loads.
This driver has been designed to drive ±12mA at the designated threshold
levels.
TheALVCHR162269Ahas“bus-hold”whichretainstheinputs’laststate

and eliminates the need for pull-up/down resistors.
