DESCRIPTION/ORDERING INFORMATION (CONTINUED)
SN74CB3Q3251
1-OF-8 FET MULTIPLEXER/DEMULTIPLEXER
2.5-V/3.3-V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH
SCDS173A – AUGUST 2004 – REVISED MARCH 2005
The SN74CB3Q3251 is a 1-of-8 multiplexer/demultiplexer with a single output-enable (OE) input. The select (S0,
S1,
S2)
inputs
control
the
data
path
of
the
multiplexer/demultiplexer.
When
OE
is
low,
the
multiplexer/demultiplexer is enabled, and the A port is connected to the B port, allowing bidirectional data flow
between ports. When OE is high, the multiplexer/demultiplexer is disabled, and a high-impedance state exists
between the A and B ports.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry prevents damaging
current backflow through the device when it is powered down. The device has isolation during power off.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
