3 Description

The TMUX6208 is a precision 8:1, single channel

multiplexer while the TMUX6209 is a 4:1, 2 channel

multiplexer featuring low on resistance and charge

injection. The devices work with a single supply (4.5V

to 36V), dual supply (±4.5V to ±18V), or asymmetric

supply (such as VDD = 12V, VSS = –5V). The

TMUX620x supports bidirectional analog and digital

signals onthe source (Sx) and drain (D) pins ranging

from VSS to VDD.

All logic control inputs support logic high levels

from 1.8 V to VDD, ensuring both TTL and CMOS

logic compatibility when operating in the valid

supply voltage range. Fail-Safe Logic circuitry allows

voltages on the control pins to be applied before

the supply pin, protecting the device from potential

damage.

The TMUX620x are part of the precision switches and

multiplexers family of devices. These devices have

very low on and off leakage currents and low charge

injection, allowing them to be used in high precision

measurement applications.
