DESCRIPTION:
The CBTLVR16292 is a single 12-bit multiplexing / demultiplexing bus
switch, which provides high speed switching. Both A and B ports have 25
Ω
series dampening resistors to minimize undershoot, reflection noise, and
charge sharing effects. The demultiplexer side has a 500
Ω resistor
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.
