24-bit bus switch
Rev. 6 — 15 December 2011
Product data sheet
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 V_CC 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 V_CC range from 2.3 V to 3.6 V.
This device is fully specified for partial power-down applications using I_OFF.
The I_OFF circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
