16-Bit I/O Expander IC

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.

FEATURES

- Wide operating supply voltage range: VDD=3 to 5.5V

- Wide operating temperature range: Ta=-20 to +75℃

• Reading of the serial data during parallel to serial data conversion

• 8 output pins or 8 input/output pins provided

• Schmitt triggered inputs (DI1,DI2,CLK,LATCH, /RESET,PULLUP)

• Parallel data inputs provided (P8 to P15)

• Open drain with selectable pull up resistance ports provided (P8 to P15)

• Normal output ports provided (P0 to P7)

• Port extension is supported

APPLICATIONS

• MCU peripheral device

• Serial bus system data communication
