Product Description

The ISO7421D is a dual-channel 1Mbps Digital Isolator, provides galvanic isolation up to 2500VRMS for 1 minute per UL. This digital isolator has two isolated channels. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. This device has TTL input thresholds and require two supply voltages, 3.3 or 5V or any combination. All inputs are 5V tolerant when supplied from a 3.3V supply.
Low power consumption, typical ICC per channel (3.3V operation) - 1.5mA
9ns Typical low propagation delay
300ps Typical low skew
50kV/µs Typical transient immunity
Over 25-year isolation integrity at rated voltage
Operates from 3.3 and 5V supply and logic levels
3.3 and 5V Level translation
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
