74LVC126A-Q100
Rev. 2 — 21 August 2018
Quad buffer/line driver with 5 V tolerant input/outputs; 3-state
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.

Pin configuration SOT108-1 (SO14) and
SOT402-1 (TSSOP14)
(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.
