74CBTLVD3245-Q100
8-bit level-shifting bus switch with output enable
Rev. 2 — 22 January 2016
Product data sheet
1. General description
The 74CBTLVD3245-Q100 is an 8-pole, single-throw bus switch. The device features a
single output enable input (OE) that controls eight switch channels. The switches are
disabled when OE is HIGH. Schmitt trigger action at control inputs makes the circuit
tolerant of slower input rise and fall times. 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.

5. Pinning information
5.1 Pinning
(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.
