FEATURES
•5 Ω switch connection between two ports
•TTL compatible control input levels
•Package options include plastic shrink small outline (SSOP) and thin shrink small outline (TSSOP)
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.
