The SN74CBTD16211 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. A diode to VCC is integrated in the circuit to
allow for level shifting from 5-V signals at the
device inputs to 3.3-V signals at the device
outputs.
The device is organized as a dual 12-bit bus
switch with separate output-enable (OE)\ inputs. It
can be used as two 12-bit bus switches or as one
24-bit bus switch. When (OE)\ is low, the associated
12-bit bus switch is on, and port A is connected to
port B. When (OE)\ is high, the switch is open, and
the high-impedance state exists between the
ports.
