description
The
SN74CBT3244
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 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 a high-impedance state exists between the two ports.
The SN74CBT3244 is characterized for operation from 0
°C to 70 °C.
