TMUX730xF ±60-V Fault-Protected, 8:1 and Dual 4:1 Multiplexers with 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. All control

inputs support logic levels from 1.8 V to 44 V, enabling

system level flexibility for controlling the multiplexer.

– Dual supply: ±5 V to ±22 V

– Single supply: 8 V to 44 V

Integrated fault protection:

•

– Overvoltage protection,

source to supplies or to Ddrain: ±85 V

– Overvoltage protection: ±60 V

– Powered-off protection: ±60 V

– Non-fault channels continue to operate with low

leakage currents

– Known state without digital inputs present

– Output clamped to the supply in overvoltage

condition

Latch-up immunity by device construction

Break-before-make switching action

Logic levels: 1.8 V to V_DD

Industry standard TSSOP and

smaller WQFN packages

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.

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

V relative to ground in both powered and powered-off

conditions.

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 enable 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).
