DESCRIPTION

The ISO72x-Q1 is a digital isolator with a logic input and output buffer separated by a silicon oxide (SiO₂)

insulation barrier. This barrier provides galvanic isolation of up to 4000 V. Used in conjunction with isolated

power supplies, this device prevents noise currents on a data bus or other circuits from entering the local ground

and interfering with or damaging sensitive circuitry.

The capacitive isolation barrier conditions, translates to a balanced signal, then differentiates a binary input

signal. Across the isolation barrier, a differential comparator receives the logic-transition information, then sets or

resets a flip-flop and the output circuit accordingly. A periodic update pulse sent across the barrier ensures the

proper dc level of the output. On failure to receive this dc refresh pulse for more than 4 μs, the response of the

device is as if the input is or not actively driven, and the failsafe circuit drives the output to a logic-high state.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
