NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device.

Exposure to absolute maximum rating conditions for extended periods may affect reliability.


Description

The CBTLVR16292 is a single 12-bit multiplexing / demultiplexing bus switch, which provides high speed switching. Both A and B ports have 25 series dampening resistors to minimize undershoot, reflection noise, and charge sharing effects. The demultiplexer side of IDT74CBTLVR16292 has a 500 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 of IDT74CBTLVR16292 is connected to B2 port and the R pulldown is connected to B1 port.
