description
The SN74CBT16211 provides 24 bits of
high-speed TTL-compatible bus switching. The
low on-state resistance of the switch allows
connections to be made with minimal propagation
delay.
The device operates as a 12-bit or 24-bit bus
switch. When 1OE is low, 1A is connected to 1B.
When 2OE is low, 2A is connected to 2B.
The SN74CBT16211 is characterized for
operation from –40°C to 85°C.
