Description
PT8311-GJ is an IC chip that functions as an I/O expander utilizing CMOS technology. It provides 16 bits serial input-parallel output and 8 bits parallel input-serial output shift register functionality. This chip can be configured into a cascading or parallel structure with 8 input pins or 16 output pins. It also boasts built-in independent registers for serial input to parallel output and parallel input to serial output, enabling reading of serial data during the parallel to serial data conversion process. PT8311-GJ comes in a 28-pin SOP package, with optimized pin assignments and application circuits for easy PCB layout and cost-saving benefits.
