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 I_off. The I_off
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.
