74CBTLV3126-Q100
4-bit bus switch
Rev. 3 — 9 October 2018
Product data sheet
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.

(1) This is not a supply pin. The substrate is
attached to this pad using conductive die attach
material. There is no electrical or mechanical
requirement to solder this pad. However, if it is
soldered, the solder land should remain floating or
be connected to GND.
