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 SN54CBT16209 and SN74CBT16209A 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.
