Description
Line Drivers are available for the HEDS-55xx/56xx series
and the HEDS-9000/9100/9200/9040/9140 series encod-
ers. The line driver oers enhanced performance when
the encoder is used in noisy environments, or when it is
required to drive long distances.
The encoder line driver utilizes an industry standard line
driver IC, AM26C31Q, which provides complementary
outputs for each encoder channel. Thus, the output
of the line driver encoder is A, A, B, B and I/I for three
channel versions. Suggested line receivers are 26LS32
and 26LS33.

HEDS-5500/5540/5600/5640 data sheet,
HEDS-90x0/91x0/92x0 data sheets,
HEDS-9000 series extended resolution data sheet, and
AM26C31Q data sheet.

Note: Avago Technologies encoders are not recommended for use in
safety critical applications. Eg. ABS braking systems, power steering,
life support systems and critical care medical equipment. Please con-
tact sales representative if more clarication is needed.
