The CBMG711, CBMG712, and CBMG713 are monolithic CMOS devices containing four independently selectable switches. These switches are designed on an advanced submicron process that provides low power dissipation yet gives high switching speed, low on resistance, low leakage currents, and high bandwidth.

They are designed to operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments and with the new generation of DACs and ADCs from Corebai. Fast switching times and high bandwidth make the parts suitable for switching USB 1.1 data signals and video signals.

The CBMG711, CBMG712, and CBMG713 contain four independent single-pole/single-throw (SPST) switches. The CBMG711 and CBMG712 differ only in that the digital control logic is inverted. The CBMG711 switches are turned on with a logic low on the appropriate control input, while a logic high is required to turn on the switches of the CBMG712. The CBMG713 contains two switches whose digital control logic is similar to the CBMG711, while the logic is inverted on the other two switches,please refer to the product function block diagram Figure 2 for details.

Each switch conducts equally well in both directions when On. The CBMG713 exhibits break-before-make switching action.

The CBMG711/CBMG712/CBMG713 are available in 16-lead TSSOP and 16-lead SOP packages. 

CBMG711/CBMG712/CBMG713 Function Block Diagrams and Truth Tables are as follows:

Figure 1 shows a switch displaying a logic input of “1”.

• Typical power consumption: (< 0.01 μW)

• TTL/CMOS compatible 

• Cell phones

• Video switching

• Communication systems

1.1.8 V to 5.5 V Single-Supply Operation. The CBMG711, CBMG712, and CBMG713 offer high performance and are fully specified and guaranteed with 3V and 5V supply rails.

2. Very Low R_ON (4.5Ω maximum at 5 V, 8Ω maximum at 3V). At supply voltage of 1.8V, R_ON is typically 35Ω over the temperature range.

3. Low On Resistance Flatness.

4. −3dB Bandwidth >200 MHz.

5. Low Power Dissipation. CMOS construction ensures low power dissipation.

6. Fast t_ON/t_OFF.

7. Break-Before-Make Switching. This prevents channel shorting when the switches are configured as a multiplexer (CBMG713 only).

8. 16-Lead TSSOP and 16-Lead SOP Packages.
