description
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.
The SN54CBT16209 is characterized for
operation over the full military temperature range
of –55°C to 125°C. The SN74CBT16209A is
characterized for operation from –40°C to 85°C.
