The below table gives the recommended operating conditions of the NVE IL510 DC-correct single channel digital isolator series including the IL510-1E: The NVE IL510 series DC-correct single channel digital isolators are ideal for the following applications The IL510 isolators can be used with Power on Reset (POR) circuits common in microcontroller applications, as the means of ensuring the output of the device is in the same state as the input a short time after power up. UL 1577 recognised IEC 6 (VDE 0884) certified High voltage endurance of 1000V RMS/1500V DCĬommon mode transient immunity of 30 kV/μs min. Typical quiescent current of 0.0013A/channel Surface-mount DC-correct single channel digital isolator Internal clocking ensures a determined power-up state (“DC correct). The IL510-1E from NVE have a pulse width distortion of 10ns with an isolation of 1KV RMS and a transient immunity of 20kV/microsecond, the A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. These devices use NVE’s patented IsoLoop® spintronic Giant Magnetoresistive (GMR) technology. The IL510-1E DC-correct single channel digital isolators from NVE are a low-cost isolator alternative to opto-couplers, operating up to 2 Mbps over an operating temperature range of −40✬ to 85✬.
