5-Ω Switch Connection Between Two Ports

TTL-Compatible Input Levels

description/ordering information

The SN54CBT16209 and SN74CBT16209A

devices provide 18 bits of high-speed

TTL-compatible bus switching or exchanging.

The low on-state resistance of the switches allows

connections to be made with minimal propagation

delay.

The devices operate as an 18-bit bus switch or a

9-bit bus exchanger, which provides data

exchanging between the four signal ports via the

data-select (S0, S1, S2) terminals.
