Octal bus switch with quad output enables

Rev. 3 — 8 September 2017

Product data sheet

1 General description

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.

2 Features and benefits
