HEDL-550x/554x, HEDL-560x/564x, HEDL-9000/9100, HEDL-9040/9140/ 92xx Encoder Line Drivers Data Sheet Description Features Available on Both Encoder Modules (HEDS-9000 Se- Line Drivers are available for the HEDS-55xx/56xx series ries) and Encoder Kit Housing (HEDS-5500 Series) and the HEDS-9000/9100/9200/9040/9140 series encod- ers. The line driver oeff rs enhanced perfor mance when Complementary Outputs the encoder is used in noisy environments, or when it is Industry Standard Line Driver IC required to drive long distances. Single 5 V Supply The encoder line driver utilizes an industry standard line Onboard Bypass Capacitor driver IC, AM26C31Q, which provides complementary outputs for each encoder channel. Thus, the output Note: Avago Technologies encoders are not recommended for use in of the line driver encoder is A, A, B, B and I/I for three safety critical applications. Eg. ABS braking systems, power steering, channel versions. Suggested line receivers are 26LS32 life support systems and critical care medical equipment.
