description/ordering information
The SN74CBTLV3384 provides ten bits of
high-speed bus switching. The low on-state
resistance of the switch allows connections to be
made with minimal propagation delay.
The device is organized as dual 5-bit bus switches
with separate output-enable (OE) inputs. It can be
used as two 5-bit bus switches or one 10-bit bus switch. When OE is low, the associated 5-bit bus switch is on,
and A port is connected to B port. When OE is high, the switch is open, and the high-impedance state exists
between the two ports.
This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that
damaging current will not backflow through the device when it is powered down. The device has isolation during
power off.
To ensure the high-impedance state during power up or power down, OE shall be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
