SGM65230
4-Bit 1-of-2 Multiplexer/Demultiplexer,
Low-Voltage High-Bandwidth Bus Switch
GENERAL DESCRIPTION
FEATURES
The SGM65230 is a 4-Bit 1-of-2 Multiplexer/Demultiplexer
and high bandwidth bus switch. It supports rail-to-rail
switching on data I/O ports and the power supply range
is designed from 2.3V to 3.6V.
● Operating Voltage Range (VCC): 2.3V to 3.6V
● Data I/Os Support 0V to 5V Signaling Levels:
0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V
● Rail-to-Rail Switching on Data I/O Ports
0V to 5V Signal Passing, VCC = 3.3V
0V to 3.3V Signal Passing, VCC = 2.5V
● High-Bandwidth Data Path
The SGM65230 has low on-resistance (RON) and low
data I/O capacitance. These features make the device
allow for minimal propagation delay and minimize
signal distortion on the data bus.
● Low On-Resistance (RON): 4Ω (TYP)
● Low Power Consumption (ICC): 0.6mA (TYP)
● Fast Switching Frequency (fOE ): 20MHz (TYP)
● 5V Tolerant I/Os with Device Powered Up or
Powered Down
It is recommended to connect a pull-up resistor
between the
pin and V
pin to ensure high
OE
CC
impedance during power-on or power-off. The ability of
the driver to absorb current can determine the minimum
value of the resistor.
● Low Input/Output Capacitance Minimizes Loading
and Signal Distortion (CIO(OFF)): 7pF (TYP)
● Data and Control Inputs Provide Undershoot
Clamp Diodes
The SGM65230 is designed with an IOFF circuitry. When
the device is powered down, the IOFF circuitry can
effectively prevent the destructive current backflow,
and the SGM65230 has an isolation function in the
state of power-off. This feature is widely used in
partial-power-down applications.
● Control Inputs Can Be Driven by TTL or 5V/3.3V
CMOS Outputs
● Support Partial-Power-Down Mode Operation
● Available in a Green TSSOP-16 Package
The SGM65230 is suitable in a variety of applications
such as high bandwidth equipment, broadband
communications and data-intensive computing systems.
