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.
