Standard ’16244-Type Pinout

5-W Switch Connection Between Two Ports

TTL-Compatible Input Levels

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.
