description/ordering information
The SN74CBTLV16211 provides 24 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 12-bit bus
switches with separate output-enable (OE)
inputs. It can be used as two 12-bit bus switches
or as one 24-bit bus switch. When OE is low, the
associated 12-bit bus switch is on, and port A is
connected to port B. 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 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.
