SLLSED3C – JUNE 2013 – REVISED JULY 2015 ISO7420FCC Low-Power Dual Channel Digital Isolator
1 Features 3 Description ISO7420FCC provides galvanic isolation up to 2500
VRMS for 1 minute per UL and 4242 VPK per VDE.
This device has two isolated channels. Each channel
has a logic input and output buffer separated by a
silicon dioxide (SiO2) insulation barrier. Used in
conjunction with isolated power supplies, this device
prevents noise currents on a data bus or other circuit
from entering the local ground and interfering with or
damaging sensitive circuitry. The suffix F indicates
low-output option in fail-safe conditions (see Table 2).
This device has integrated noise filter for harsh
environments where short noise pulses may be
present at the device input pins. 1 Signaling Rate: 50 Mbps (5-V Supplies)
Output is Low in Default Mode
Integrated Noise Filter on the Input Pins
Low Power Consumption: Typical ICC per Channel …
