Corebai Microelectronics CBMG708ATS16

CBMG708/CBMG709 are low-voltage CMOS analog multiplexers, comprising eight single channels and four differential channels respectively. The CBMG708 switches one of eight inputs (S1 to S8) to a common output D, determined by 3-bit binary address lines A0, A1, and A2. The CBMG709 switches one of four differential inputs to a common differential output determined by 2-bit binary address lines A0 and A1. The EN input on both devices is used to enable or disable the device. When disabled, all channels are turned off.

The low power consumption and 1.8 V to 5.5 V supply voltage range make the CBMG708/CBMG709 ideal for battery-powered portable instruments. All channels break before making during switching operations, preventing momentary short circuits when switching channels.

These switches feature low power consumption, high switching speed, very low on-resistance, and low leakage current. On-resistance is in the range of a few ohms, tightly matched between switches, and very flat across the entire signal range. These switches can operate as multiplexers or demultiplexers, with input signal range extending to the supply rails.

The CBMG708/CBMG709 are both available in TSSOP16 packages.
