74CBTLV3126 4-bit bus switch Rev. 5 9 October 2018 Product data sheet 1. General description The 74CBTLV3126 provides a 4-bit high-speed bus switch with separate output enable inputs (1OE to 4OE). 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 LOW. To ensure the high-impedance OFF-state during power-up or power-down, nOE should be tied to the GND through a pull-down 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 range from 2.3 V to 3.6 V. CC This device is fully specified for partial power-down applications using I . The I circuitry OFF OFF disables the output, preventing the damaging backflow current through the device when it is powered down. 2.
