Texas Instruments ISO7230C
The ISO7230 and ISO7231 are triple-channel digital isolators each with multiple channel configurations and output enable functions. These devices have logic input and output buffers separated by TI’s silicon dioxide (SiO2) isolation barrier.FEATURES
●1 25 and 150-Mbps Signaling Rate Options – Low Channel-to-Channel Output Skew; 1 ns Maximum – Low Pulse-Width Distortion (PWD); 2 ns Maximum – Low Jitter Content; 1 ns Typical at 150 Mbps● Typical 25-Year Life at Rated Working Voltage (See Application Note SLLA197 and Figure 19)
● 4-kV ESD Protection
● Operate With 3.3-V or 5-V Supplies
● 3.3-V and 5-V Level Translation
● High Electromagnetic Immunity (See Application Note SLLA181)
● –40°C to 125°C Operating Range
● Safety and Regulatory Approvals – 4000-VPK Isolation per DIN V VDE V 0884-10 and DIN EN 61010-1 – 2500 VRMS Isolation for 1 minute per UL 1577 – CSA Component Acceptance Notice 5A and IEC 60950-1 End Equipment Standard 2
APPLICATIONS
● Industrial Fieldbus● Computer Peripheral Interface
● Servo Control Interface
● Data Acquisition 3
DESCRIPTION
Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
