NVE IL511-1E

NVE IL511-1E
The IL511-1E DC-correct dual 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 −40ºC to 85ºC. These devices use NVE’s patented IsoLoop® spintronic Giant Magnetoresistive (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The IL511-1E from NVE have a pulse width distortion of 10ns with an isolation of 1KVRMS and a transient immunity of 50kV/microsecond, internal refresh clock which ensures the synchronisation of input and output within 9 μs of the supply passing the 1.5 V threshold.

  • Surface-mount DC-correct digital isolator
  • Unidirectional two channel isolation
  • Power supply between 3V and 5V
  • Maximum speed of 2Mbps
  • Typical quiescent current of 0.0013A/channel
  • High voltage endurance of 1000VRMS/1500VDC
  • Operating temperature range of −40°C to +85°C
  • Common mode transient immunity of 30 kV/μs min. and 50 kV/μs typ.
  • Low EMC footprint
  • Pulse width distortion of 10ns
  • Propagation delay of 25ns
  • Barrier life of 44000 years
  • UL 1577 recognised; IEC 60747-5-5 (VDE 0884) certified
  • 8-pin MSOP package

The IL511 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.

The NVE IL511 series DC-correct two channel digital isolators are ideal for the following applications

  • ADC's and DAC's
  • Digital filedbus
  • Multiplexed data transmission
  • Data interfaces
  • Board to board communication
  • Digital noise reduction
  • Ground loop elimination
  • Parallel bus
  • Peripheral interfaces
  • Logic level shifting
