DESCRIPTION:
technology. The ALVCH16276 device is a high-speed, bidirectional, 12-bit,
registered, bus multiplexer for use in synchronous memory interleaving
applications. All registers have a common clock and use a clock enable (CExxx)
on each data register to control data sequencing. The output enables and mux
select (OEA, OEB and SEL) are also under synchronous control allowing
direction changes to be edge triggered events.
the A port and either/both of the B ports. The clock enable (CE1B, CE2B, CEA1B
and CEA2B) inputs control data storage. Both B ports have a common output
enable (OEB) to aid in synchronously loading the B registers from the B port.
driver is capable of driving a moderate to heavy load while maintaining speed
performance.
ever the input goes to a high impedance. This prevents floating inputs and
eliminates the need for pull-up/down resistors.
This 12-bit synchronous bus exchanger is built using dual metal CMOS
The ALVCH16276 has three 12-bit ports. Data may be transferred between
The ALVCH16276 has been designed with a ±24mA output driver. This
The ALVCH16276 has “bus-hold” which retains the inputs’ last state when-
