SLLSE39 –JUNE 2010

Low-Power 5 KV(rms) Dual Digital Isolators

Check for Samples: ISO7520, ISO7521

The devices have TTL input thresholds and require

two supply voltages, 3.3V or 5V, or any combination.

All inputs are 5-V tolerant when supplied from a 3.3-V

supply.

FEATURES

•

Highest Signaling Rate: 1 Mbps

Propagation Delay Less Than 20 ns

Low Power Consumption

Note: The ISO7520 and ISO7521 are specified for

signaling rates up to 1 Mbps. Due to their fast

response time, under most cases, these devices will

also transmit data with much shorter pulse widths.

Designers should add external filtering to remove

spurious signals with input pulse duration < 20 ns if

desired.

Wide Ambient Temperature: –40°C to 105°C

DESCRIPTION

The ISO7520 and ISO7521 provide double galvanic

isolation of up to 5KVrms for 1 minute per UL. These

digital isolators have two isolated channels with

uni-directional (ISO7520) and bi-directional (ISO7521)

channel configurations. Each isolation channel has a

logic input and output buffer separated by a silicon

oxide (SiO₂) insulation barrier. 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.

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.
