description

The SN74CBT16861 provides 20 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 dual 10-bit switch

with separate 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.
