1600 SERIES Dual and Quad Data-bus Isolators features Logic Translation Bi-Directional Invert / Non-Invert TTL-CMOS Convert 3V-5V convert Toroidal construction Low Profile Dual or Quad packs 700VDC Isolation pin connections 10 Pin DIL (top view) The 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. 10 9 7 6 N N 1 1 1 2 4 5 16 Pin DIL (top view) 16 1 15 14 13 12 11 10 9 N N N N 1 1 1 1 2 3 4 5 6 7 4 - 1600 SERIES description 8 Pulse Transformers 1 1600 SERIES Dual and Quad Data-bus Isolators absolute maximum ratings over operating free air temperature range Operating free air temperature range . . . . . . . .
