LS7266R1
Description:
The
LS7266R1
is an LSI monolithic CMOS building block useful in motion
control applications. The two 24-bit multimode counters, registers, and
logic enables a microprocessor to track the speed, direction, position, and
index of one or two optical incremental encoders. In addition to an 8-bit data
bus, programmable real-time inputs and outputs are provided for hardware
based control functions and status indication.
Note:
US Digital has already designed the IC's on this data sheet into various
products. Please see the
PC7266, AD5
or
ED2.
