The SN74CBT16213 provides 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.

The 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–S2) terminals.
The SN74CBT16213 is characterized for
operation from –40°C to 85°C.
