SLLSEN3 – DECEMBER 2015 ISO7421-EP Low-Power Dual Digital Isolators
1 Features 3 Description The ISO7421-EP device provides galvanic isolation
up to 2500 VRMS for 1 minute per UL. The ISO7421EP device 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, the device
prevents noise currents on a data bus or other circuit
from entering the local ground and interfering with or
damaging sensitive circuitry. 1 Highest Signaling Rate: 1 Mbps
Low Power Consumption, Typical ICC per Channel
(3.3-V Operation): 1.5 mA
Low Propagation Delay – 9 ns Typical
Low Skew – 300 ps Typical
Wide TJ Range: –55°C to 136°C
50-kV/Ојs Transient Immunity, Typical
Over 25-Year Isolation Integrity at Rated Voltage
Operates From 3.3-V and 5-V Supply and Logic …
