PT8300 is an I/O expander utilizing CMOS Technology providing 16 bits serial input-parallel output and 8 bits parallel input-serial output shift register function. 8 input pins or 16 output pins can be configured to a cascading or parallel structure. Reading of serial data during the parallel to serial data conversion is enabled by the built-in independent registers for serial input to parallel output and parallel input to serial output. Housed in 28 pins, SO Package, PT8300 provides 8 input or 16 output pins which can be configured into a cascading structure. Pin assignments and application circuits are optimized for easy PCB layout and cost saving benefits.
