Data Acquisition

(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

DESCRIPTION/ORDER INFORMATION

The ISO721, ISO721M, ISO722, and ISO722M are digital isolators 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, these devices prevent noise currents on a data bus or other circuits

from entering the local ground, and interfering with or damaging sensitive circuitry.

A binary input signal is conditioned, translated to a balanced signal, then differentiated by the capacitive isolation

barrier. 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 is sent across the barrier to ensure

the proper dc level of the output. If this dc-refresh pulse is not received for more than 4 µs, the input is assumed

to be unpowered or not being 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.

Products conform to specifications per the terms of Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
