TMUX7308F, TMUX7309F

SCDS403B – FEBRUARY 2021 – REVISED DECEMBER 2021

TMUX730xF ±60-V Fault-Protected, 8:1 and Dual 4:1 Multiplexers with Latch-Up

Immunity and 1.8-V Logic

1 Features

3 Description

•

Wide supply range:

The TMUX7308F and TMUX7309F are modern

complementary metal-oxide semiconductor (CMOS)

analog multiplexers in 8:1 (single ended) and 4:1

(differential) configurations. The devices work well

with dual supplies (±5 V to ±22 V), a single supply (8

V to 44 V), or asymmetric supplies (such as V_DD= 12

V, V_SS= –5 V). The overvoltage protection is available

in powered and powered-off conditions, making the

TMUX7308F and TMUX7309F devices suitable for

applications where power supply sequencing cannot

be precisely controlled.

– Dual supply: ±5 V to ±22 V

– Single supply: 8 V to 44 V

Integrated fault protection:

– Overvoltage protection, source to supplies or

source to drain: ±85 V

– Overvoltage protection: ±60 V

– Powered-off protection: ±60 V

– Non-fault channels continue to operate

– Known state without logic inputs present

– Output clamped to the supply in overvoltage

condition

•

The device blocks fault voltage up to +60 V or –60

V relative to ground in both powered and powered-off

conditions. When no power supplies are present, the

switch channels remain in the OFF state regardless of

switch input conditions and logic control status. Under

normal operation conditions, if the analog input signal

level on any Sx pin exceeds the supply voltage (V_DD

or V_SS) by a threshold voltage (V_T), the channel turns

OFF and the Sx pin becomes high impedance. When

the fault channel is selected, the drain pin (D or Dx) is

pulled to the supply (V_DDor V_SS) that was exceeded.

Latch-up immune

1.8-V Logic capable

Fail-safe logic: up to 44 V independent of supply

Integrated pull-down resistor on logic pins

Break-before-make switching

Industry standard TSSOP and

smaller WQFN packages

2 Applications

•

Factory automation and control

Programmable logic controllers (PLC)

Analog input modules

Semiconductor test equipment

Battery test equipment

The low capacitance, low charge injection, and

integrated fault protection enables the TMUX7308F

and TMUX7309F devices to be used in front end

data acquisition applications where high performance

and high robustness are both critical. The devices are

available in a standard TSSOP package and smaller

WQFN package (ideal if PCB space is limited).
