74CBTLVD3245-Q100
8-bit level-shifting bus switch with output enable
Rev. 3 — 16 April 2019
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 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.
