bus multiplexer/transceiver for use in high-speed mcroprocessor applica-
tions. This bus exchanger supports memory interleaving with latched out-
puts on the B ports and address multiplexing with latched inputs on the B
ports.
The LVCH16260A tri-port bus exchanger has three 12-bit ports. Data
may be transferred between the A port and either/both of the B ports. The
latch enable (LE1B, LE2B, LEA1B and LEA2B) inputs control data storage.
When a latch-enable input is high, the latch is transparent. When a latch-
enable input is low, the data at the input is latched and remains latched until
the latch enable input is returned high. Independent output enables (
OE1B
and
OE2B
) allow reading fromone port while writing to the other port.
All pins of the 12-bit Bus Exchanger can be driven fromeither 3.3V or
5V devices. This feature allows the use of the device as a translator in a
mxed 3.3V/5V supply system
The LVCH16260A has been designed with a ±24mA output driver. The
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The LVCH16260A has “bus-hold” which retains the inputs’ last state
whenever the input goes to a high impedance. This prevents floating inputs
and elimnates the need for pull-up/down resistors.
