HCTL-2032, HCTL-2032-SC, HCTL-2032-SCT, HCTL-2022
Quadrature Decoder/ Counter Interface ICs
Data Sheet
Description
The HCTL-20XX-XX is CMOS ICs that perform the quadra-
ture decoder, counter, and bus interface function. The
HCTL-20XX-XX is designed to improve system perfor-
mance 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 effec-
tive hardware solution. The HCTL-20XX-XX consists of a
quadrature decoder logic, a binary up/down state coun-
ter, and an 8-bit bus interface. The use of Schmitt-trig-
gered CMOS inputs and input noise filters allows reliable
operation in noisy environments. The HCTL-20XX-XX
contains 32-bit counter and provides LSTLL compatible
tri-state output buffers. Operation is specified for a tem-
perature range from -40 to +100°C at clock frequencies
up to 33MHz.
The HCTL-2032 and HCTL-2032-SC have dual-axis capa-
bility and index channel support. Both devices can be
programmed as 4x/2x/1x count mode. The HCTL-2032
and HCTL2032-SC also provides quadrature decoder out-
put signals and cascade signals for use with many stan-
dard computer ICs.
The HCTL-2022 has most of the HCTL-2032 features, but
it can only supports single axis and fixed at 4x count
mode. The HCTL-2022 doesn’t provide decoder output
and cascade signals.
