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

the high-impedance state exists between the two

ports.
