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.  
APPLICATIONS  
Infrastructure Equipment  
Wired and Wireless IP Phones  
The SGM65230 is available in a Green TSSOP-16  
package. It operates over an operating temperature  
range of -40to +125.  
Optical Networking: Video over Fiber and EPON
