Datasheet
1. General description
2. Features
The CBT3244A provides eight bits of high-speed TTL-compatible bus switching in a
standard '244 device pinout. The low ON-state resistance of the switch allows connections
to be made with minimal propagation delay.
The CBT3244A device is organized as two 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 high-impedance
state exists between the two ports.
The CBT3244A is characterized for operation from 40 C to +85 C.
