SN74CBT3244
OCTAL FET BUS SWITCH

description/ordering information (continued)
The SN74CBT3244 provides eight bits of high-speed TTL-compatible bus switching. The SOIC, SSOP, TSSOP,
and TVSOP packages provide 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 the high-impedance state exists between the two ports.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
