DESCRIPTION

TThe 1600 series are dual or quad isolation
transformer packs for use in digital circuits.
They are particularly suited to isolating
microprocessor bus connections and
performing logic level translation.
Being completely passive, power savings
are offered over opto-coupled or emitter
follower solutions.

Operating free air temperature range 0°C to 70°C
Storage temperature range --40°C to 125°C
Lead Temperature 1.5mm from case for 10 seconds 300°C
Isolation voltage (flash tested for 1 second) 700VDC
Insulation resistance at 500VDC >10GΩ
