74CBTLV3257-Q100
Quad 1-of-2 multiplexer/demultiplexer
Rev. 1 — 4 July 2013
Product data sheet
1. General description
The 74CBTLV3257-Q100 provides a quad 1-of-2 high-speed multiplexer/demultiplexer
with common select (S) and output enable (OE) inputs. The low ON resistance of the
switch allows inputs to be connected to outputs without adding propagation delay or
generating additional ground bounce noise. When pin OE = LOW, one of the two switches
is selected (low-impedance ON-state) with pin S. When pin OE = HIGH, all switches are in
the high-impedance OFF-state, independent of pin S. To ensure the high-impedance
OFF-state during power-up or power-down, OE should be tied to the V
CC
through a
pull-up 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.

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.
