description/ordering information

The SN74CBTLV16212 provides 24 bits of

high-speed bus switching or exchanging. The low

on-state resistance of the switch allows

connections to be made with minimal propagation

delay.

The device operates as a 24-bit bus switch or a

12-bit bus exchanger, which provides data

exchanging between the four signal ports via the

data-select (S0, S1, S2) terminals.

This device is fully specified for

partial-power-down applications using Ioff. The Ioff

feature ensures that damaging current will not

backflow through the device when it is powered

down. The device has isolation during power off.

The SN74CBTLV16212 is specified by the

break-before-make feature to have no through

current when switching between B ports.
