description

The SN74CBT16245 device provides 16 bits of

high-speed TTL-compatible bus switching in a

standard ’16245 device pinout. The low on-state

resistance of the switch allows connections to be

made with minimal propagation delay.

The device is organized as two 8-bit low-impedance

switches with separate output-enable (OE) inputs.

When OE is low, the switch is on, and data can

flow from the A port to the B port, or vice versa.

When OE is high, the switch is open, and the

high-impedance state exists between the two

ports.
