Mitsubishi M62342P, M62342FP Datasheet

8-BIT 2CH D-A CONVERTER WITH BUFFER AMPLIFIERS
GENERAL DESCRIPTION
The M62342P,FP is a CMOS 2 channel D-A converter with output buffer amplifiers. It can communicate with a microcontroller via few wiring thanks to the adoption of the three-line DI,CLK,LD. The output buffer amplifier employs AB class output with sinking and sourcing capability of more than 1.0mA , and an output voltage range is nearly between ground and Vcc.
FEATURES
10bit serial data input (3-wire serial transfer method)
Wide output voltage range
Nearly between ground and Vcc(0 to 5V)
High output current drive capability
over ±1.0mA

Shift clock input terminal. Input signal at DI pin is input to 10-bit shift register at rise of shift clock pulse.
When H-level signal is input to this terminal,the value stored in 10-bit shift register is loaded in decoder and D-A converter output register.
