Introduction

AI Translation

The ISO7421-EP device provides galvanic isolation rated to 2500 V_RMS for up to 1 minute in accordance with UL standards. The ISO7421-EP device has two isolated channels. The logic input and output buffers of each isolated channel are separated by a silicon dioxide (SiO₂) insulation barrier. When used with an isolated power supply, this device prevents noise currents on data buses or other circuits from entering the local ground and interfering with or damaging sensitive circuits. This device features TTL input thresholds and requires two supply voltages of 3.3 V or 5 V, or any combination thereof. When powered by a single 3.3 V supply, all inputs are 5 V tolerant. The ISO7421-EP device is rated for signal transfer rates up to 1 Mbps. Due to its short response time, this device will also transmit data with shorter pulse widths in most cases. If necessary, designers should add external filtering to reject spurious signals with input pulse durations <20 ns.
