description/ordering information
8
The ’CBT16212A devices provide 24 bits of
high-speed TTL-compatible bus switching or
exchanging. The low on-state resistance of the
switch allows connections to be made with
minimal propagation delay.

Each device operates as a 24-bit bus switch or a
12-bit bus exchanger that provides data
exchanging between the four signal ports via the
data-select (S0, S1, S2) terminals.
