description
The SN74CBTS16212 provides 24 bits of
high-speed TTL-compatible bus switching or
exchanging with Schottky diodes on the I/Os to
clamp undershoot. 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–S2) terminals.
The SN74CBTS16212 is characterized for
operation from –40°C to 85°C.
