ORDERING
OPTIONS
* Pin 1 has internal pull-up resistor which allows Pin 1 to be left floating (enable high)
A bypass capacitor 0.01 F is required from Vdd to Gnd. Reflow profile, see appendix E.
Test circuit, waveforms, please see appendix B. Marking, see appendix G.
Environmental and mechanical specifications, see appendix C. Group 2.
Application notes, see appendix A. Tape and Reel, see appendix H.(1,000 pcs./reel).
