74LVC126A-Q100
Quad buffer/line driver with 5 V tolerant input/outputs; 3-state
Rev. 1 — 26 May 2014
Product data sheet
1. General description
The 74LVC126A-Q100 consists of four non-inverting buffers/line drivers with 3-state
outputs, which are controlled by the output enable input (nOE). A LOW at nOE causes the
outputs to assume a high-impedance OFF-state.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs.
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.
