ISO721
Overview
The ISO721, ISO721M, ISO722, and ISO722M devices are digital isolators with a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. This barrier provides galvanic isolation of up to 4000VPK per VDE 0884-17.
- 100 and 150Mbps signaling rate options
- Propagation delay is 12ns typical.
- Pulse skew is 0.5ns typical.
- Low-power sleep mode
- Typical 28year life at rated working voltage (see Isolation Lifetime Projection)
- High electromagnetic immunity (see application note ISO72x Digital Isolator Magnetic-Field Immunity)
- Failsafe output
- Drop-in replacement for most opto and magnetic isolators
- Operates from 3.3V and 5V supplies
- -40°C to +125°C operating temperature range
