Like polarity drive circuit

Published:2011/4/21 22:49:00 Author:Nicole | Keyword: like polarity

Using shield wire, twisted pair or coaxial cable, the 74S140 like polarity driver transports the data to HCPL-2602 optical coupling receiver with high data transmission speed. The reflex action produced by active terminal receiver has no influence on the performance. To connect capacitance C and in series with resistance R, it can make the data transmission speed reach the possible maximum speed. C should as large as possible, it is no need to prevent the regulator tube of receiver from turning off during the input singal negative bias. If tPHL=tPLH, then it will obtain the maximum data transmission speed.   (View)

On/off control circuit

Published:2011/4/22 1:15:00 Author:Nicole | Keyword: On/off control

CA3062 combined photodetector and power amplifier can produce on/off output by optical signal. The output transistor of IC should be saturated or closed, prevent the temperature from rising. When the light of IR LED falls on the optical input terminal of IC, complementary output can select the load which is normal open or normal off. After blocking the light path, it will produceopposite load situation.   (View)
