Encoder Line Drivers
Technical Data
HEDL-550x/554x
HEDL-560x/564x
HEDL-9000/9100
HEDL-9040/9140
Features
• Available on Both Encoder
Modules (HEDS-9000
Series) and Encoder Kit
Housing (HEDS-5500 Series)
• Complementary Outputs
• Industry Standard Line
Driver IC
• Single 5 V Supply
The 70°C version utilizes an
industry standard line driver IC
(26LS31) which provides comple-
mentary outputs for each encoder
channel. The 100°C version utilizes
an industry standard line driver IC,
26C31, which provides comple-
mentary 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
• Onboard Bypass Capacitor
• 70°C and 100°C Versions
Available

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
contact sales representative if
more clarification is needed.

For additional information,
please refer to:
HEDS-5500/5540/5600/5640
data sheet,
HEDS-90x0/91x0/92x0 data
sheets,

resolution data sheet, and
26LS31 data sheet.
Line Drivers are available for the
HEDS-55xx/56xx series and the
HEDS-9000/9100/9200/9040/
9140 series encoders. The line
driver offers enhanced perform-
ance when the encoder is used in
noisy environments, or when it is
required to drive long distances.
