1. O'chirish sxemasi shassi erdan ichki izolyatsiya qilingan.
2. TFAULT ochiq kollektor/drenaj chiqishi bo‘lib, agar mo‘ljallangan bo‘lsa, asosiy platada 4,7k – 10k Ohm rezistor bilan tortilishi kerak.
2. TFAULT ochiq kollektor/drenaj chiqishi bo‘lib, agar mo‘ljallangan bo‘lsa, asosiy platada 4,7k – 10k Ohm rezistor bilan tortilishi kerak.
foydalanish uchun.Yuqori kuchlanish 2,0 V dan Vcc + 0,3 V gacha bo'lishi kerak.Yuqori chiqish transmitterning noto'g'ri ekanligini ko'rsatadi, yoki TX egilishidan kelib chiqadi
oqim yoki TX chiqish quvvati oldindan o'rnatilgan signal chegaralaridan oshib ketadi.Past chiqish normal ishlashni ko'rsatadi.Past holatda,
chiqish 2.0V ga tortiladi yoki ochiq, TDIS<0.8V da yoqilgan.
4. Asosiy platada 4,7k - 10 kohm bilan 2,0V dan 3,6V gacha bo'lgan kuchlanishga tortilishi kerak.
