ISO7141CCDBQ .

The ISO7141CCDBQ is a 4242VPK small-footprint and low-power 3/1 quad channel Digital Isolator with noise filter. This isolator provides galvanic isolation up to 2500VRMS for 1 minute per UL and 4242VPK per VDE. This device is capable of 50Mbps maximum data rate with 5V supplies and 40Mbps maximum data rate with 3.3 or 2.7V supplies, with integrated filters on the inputs for noise-prone applications. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used with isolated power supplies, this device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The devices have TTL input thresholds.

• Robust design with integrated noise filter
• 23ns Typical low propagation delay
• ±50kV/µs Typical transient immunity
• Long life with SiO2 isolation barrier
• Green product and no Sb/Br
