4242-VPK Small-Footprint and Low-Power 3/1 Quad Channel Digital Isolator with Noise Filter

Recommended alternative parts

  • ISO7641FC  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   ISO7641FC is equivalent to the ISO7141CC but it in a larger DW package, is fail safe low and has speed of 25Mbps.

Description

ISO7131, ISO7140, and ISO7141 provide galvanic isolation up to 2500 VRMS for 1 minute per UL and 4242 VPK per VDE. ISO7131 has three channels with two forward and one reverse-direction channels. ISO7140 and ISO7141 are quad-channel isolators; ISO7140 has four forward, ISO7141 has three forward and one reverse-direction channels. These devices are capable of 50 Mbps maximum data rate with 5V supplies and 40Mbps maximum data rate with 3.3V or 2.7V supplies, with integrated filters on the inputs for noise-prone applications. The suffix F indicates that default output state is low; otherwise, the default output state is high.

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 circuits from entering the local ground and interfering with or damaging sensitive circuitry. The devices have TTL input thresholds and can operate from 2.7 V, 3.3 V, and 5 V supplies. All inputs are 5V tolerant when supplied from a 2.7V or 3.3V supply.
