description
The ’CBT16244 devices provide 16 bits of
high-speed TTL-compatible bus switching in a
standard ’16244 device pinout. The low on-state
resistance of the switch allows connections to be
made with minimal propagation delay.
These devices are organized as four 4-bit
low-impedance switches with separate
output-enable (OE) inputs. When OE is low, the
switch is on, and data can flow from port A to port
B, or vice versa. When OE is high, the switch is
open, and the high-impedance state exists
between the two ports.
