The 74CBTLV3253-Q100 provides a dual 1-of-4 high-speed multiplexer/demultiplexer
with two common select inputs (S0, S1) and two output enable inputs (1OE, 2OE). 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 nOE = LOW,
one of the four switches is selected (low-impedance ON-state) with pins S0 and S1. When
pin nOE = 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,
nOE should be tied to the VCC through a pull-up resistor. The current-sinking capability of
the driver determines the minimum value of the resistor.
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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
