DESCRIPTION
The M66006 is a semiconductor integrated circuit which has 12-bit shift register function to execute serial-parallel conversion and parallel-serial conversion.
Because a serial-parallel shift register and a parallel-serial shift register are independently built in this IC, it is possible to read serial input data to a shift register while converting parallel data into serial data. Also, parallel data I/O pins can be set to input mode or output mode bit-by-bit.
The M66006 can be widely used for I/O port expansion of MCU, serial bus system data communication, etc.

FEATURES
• Bi-directional serial data communication with MCU
• Read of serial data during parallel-serial conversion.
• Bit resolution of serial data I/O
• Low power dissipation (50µW/package max.)
                                       (VCC=5V, Ta=25°C, in quiescing)
• Schmitt input (DI, CLK, S, CS)
• Open drain output (DO, from D1 to D12)
• Parallel data I/O (from D1 to D12)
• Wide operating supply voltage range (VCC=2 to 6V)
• Wide operating temperature range (Ta=–20 to 75°C)

APPLICATION
   Serial-parallel data conversion, parallel-serial data conversion, serial bus control by MCU.
