1. General description

The 74CBTLV16211 provides a dual 12-bit high-speed bus switch with separate output

enable inputs (1OE, 2OE). The low on-state resistance of the switch allows connections to

be made with minimal propagation delay. The switch is disabled (high-impedance

OFF-state) when the output enable (nOE) input is HIGH.

To ensure the high-impedance OFF-state during power-up or power-down, 1OE and 2OE

should be tied to the VCC through a pull-up resistor. The minimum value of the resistor is

determined by the current-sinking capability of the driver.

Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall

times across the entire VCC range from 2.3 V to 3.6 V.

This device is fully specified for partial power-down applications using IOFF.

The IOFF circuitry disables the output, preventing the damaging backflow current through

the device when it is powered down.
