1. General description
The 74CBTLV3126-Q100 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 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 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
