description/ordering information

The SN74CBTLV16210 provides 20 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 10-bit bus

switches with separate output-enable (OE)

inputs. It can be used as two 10-bit bus switches

or as one 20-bit bus switch. When OE is low, the

associated 10-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.
