SAFETY AND REGULATORY
APPROVALS
• 6000 V_PK / 4243 V_RMS for 1 Minute per UL 1577
(approved)
• VDE Approval for DIN EN 60747-5-2 (VDE 0884
Rev. 2), 1414 V_PK Working Voltage (approved)
• CSA Component Acceptance Notice 5A, IEC

DESCRIPTION
ISO7640FM and ISO7641FM provide galvanic isolation up to 6 KV_PK for 1 minute per UL and VDE. These
devices are also certified up to 5 KV_RMS Reinforced isolation at a working voltage of 400 V_RMS per end equipment
standards EN/UL/CSA 60950-1 and 61010-1. ISO7640F and ISO7641F are quad channel isolators; ISO7640F
has four forward and ISO7641F has three forward and one reverse direction channels. Suffix F indicates that
output defaults to Low-state in fail-safe conditions (see Table 1). M-Grade devices are high speed isolators
capable of 150 Mbps data rate with fast propagation delays
