HCTL-2016 #PLC

HCTL-2020 #PLC

Surface Mount Quadrature

Decoder/Counter Interface ICs

Technical Data

Features

• 20 Pin PLCC Surface Mount

Package

• All Features of the HCTL-

2016 and HCTL-2020 PDIP

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: Agilent 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.

Pinouts

ESD WARNING: NORMAL HANDLING PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC

DISCHARGE.
