DESCRIPTION
The CBT16211 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 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 a high-impedance state exists between
the ports.
The CBT16211 is characterized for operation from –40 to 85
°C.
