iC-DY6818 32-BIT SERIAL INPUT LATCHED PUSH/PULL DRIVER er Driv Monostable er Driv Monostable r e v i r river DD Monostable 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.
