LS7166
Encoder to Microprocessor Interface Chip
Chips
The
LS7166
is an LSI monolithic CMOS building block useful in motion control
applications. The 24-bit multi-mode counter register and logic enables a microproces-
sor to track the speed, direction, and position of an optical incremental shaft encoder.
In addition to an 8-bit data bus, programmable realtime inputs and outputs are provided
for hardware based control functions and status indication.
Note:
US Digital has already designed the ICs on this data sheet into various products.
Please see the
PC7166
,
AD4-A
and
AD6
data sheets.
