in digital closed loop motion

control systems and digital data

input systems. It does this by

shifting time intensive quadrature

decoder functions to a cost

effective hardware solution. The

entire HCTL-20XX family con-

sists of a 4x quadrature decoder,

a binary up/down state counter,

and an 8-bit bus interface. The

use of Schmitt-triggered CMOS

inputs and input noise filters

allows reliable operation in noisy

environments. The HCTL-2000

contains a 12-bit counter. The

HCTL-2016 and 2020 contain a

16-bit counter. The HCTL-2020

also contains quadrature decoder

output signals and cascade

signals for use with many

standard counter ICs. The HCTL-

20XX family provides LSTTL

compatible tri-state output

buffers. Operation is specified for

a temperature range from -40 to

+85

°C at clock frequencies up to

14 MHz.
