PT8300
DESCRIPTION
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, SOP 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.
