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 I
off
. The I
off
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 V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
