iC-DY6818 is a 32-bit shift register with 32 output channels with
minimum 25 mA per channel. The typical serial data input frequency is 33 MHz maximum. Output channel supply ranges from
8 to 36 V and input channel supply from 3.3 to 5.5 V for industrial
applications. Integrated free-wheeling diodes at the output
channels allow operation of inductive loads. iC-DY6818 allows
for daisy chaining of multiple devices. The iC-DY6818 is pincompatible with the A6818.
