description/ordering information
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.

2OE
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.
