IDT74CBTLV16292
DESCRIPTION:
The CBTLV16292 is a single 12-bit multiplexing / demultiplexing bus
switch, which provides high speed switching. This device has very low ON
resistance, resulting in under 250ps propagation delay throught the switch.
The demultiplexer side has a 500鈩?resistor (R pulldown) termination to
GND to eliminate floating nodes.
When the select (S) input is low, the A port is connected to the B1 port,
and the R pulldown is connected to the B2 port. Similarly, when the S input
is high, A port is connected to B2 port and the R pulldown is connected to
B1 port.
APPLICATIONS:
鈥?3.3V High Speed Bus Switching and Bus Isolation
鈥?Resource sharing
