DESCRIPTION
The UTC M62364 is a CMOS 8-bit, 8-ch D/A converter
having a multiplying function and output buffer amplifiers. It
has a serial data input and can easily communicate with a
microcontroller by the simple three-wiring method (DIN, CLK,
LD).
The output buffer amplifiers operating in AB-class has
both sinking and driving capabilities of 1.0mA or more and
can operate in a whole supply range from VDD to GND.
The IC is suitable for a use in automatic adjustment
applications in conjunction with a MCU by utilizing the
terminal Do for a cascading connection.

FUNCTION
Serial data input
Serial data output
Shift clock input. Input data of DIN are taken into the 12-bit shift register on a rising edge of
the clock
A low state enables data loading to the 12-bit shift register. During a rising edge of LD, the
data will be loaded to the output register
Reset 8-bit latches
