description
The SN74CBT3861 provides ten 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 one 10-bit switch with
a single output-enable (OE) input. When OE is
low, the 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 two
ports.
The SN74CBT3861 is characterized for operation
from –40°C to 85°C.
