CBT16213

DESCRIPTION

The CBT16213 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 CBT16213 operates as 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 CBT16213 is characterized for operation from –40 to +85 °C.
