74CBTLV3253PW,118

74CBTLV3253PW,118 is a dual 1-of-4 multiplexer/demultiplexer. It provides a dual 1-of-4 high-speed multiplexer/demultiplexer with two common select inputs (S0, S1) and two output enable inputs. The low ON resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When pin n active-low OE = LOW, one of the four switches is selected (low-impedance ON-state) with pins S0 and S1. When pin n active-low OE = HIGH, all switches are in the high-impedance OFF-state, independent of pins S0 and S1. To ensure the high-impedance OFF-state during power-up or power-down, n active-low OE 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 2.3V to 3.6V.
