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.
