HCTL-2016 #PLC
HCTL-2020 #PLC
Surface Mount Quadrature Decoder/Counter Interface ICs
Data Sheet
Description
The HCTL-2016 #PLC and HCTL-2020 #PLC are
quadrature decoder/counter interface ICs in a 20 pin
PLCC (plastic leaded chip carrier) surface mount
package. These CMOS ICs interface incremental
encoders to microprocessors by performing the
quadrature decoder, counter, and bus transfer
functions.
The HCTL-2016 #PLC and HCTL-2020 #PLC have all
of the same features, functions, and operating
characteristics as the HCTL-2016 and HCTL-2020
PDIP (plastic dual-in-line package).
For further information on the operation and
function of the HCTL-2016 #PLC and 2020 #PLC,
please refer to the HCTL-2000/HCTL-2016/
HCTL-2020 data sheet.
Applications
Typical applications include interfacing incremental
encoders to microprocessors and interfacing digital
potentiometers to digital data input buses.
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 contact sales representative if more clarification
is needed.
