The SN74CBT16211A 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 dual 12-bit bus switch or
single 24-bit bus switch. When 1OE is low, 1A is
connected to 1B. When 2OE is low, 2A is
connected to 2B.
