FEATURES Logic Translation Bi-Directional Invert / Non-Invert TTL-CMOS Convert 3V-5V convert Toroidal construction Low Profile Dual or Quad packs 700VDC Isolation 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.
