M62370GP
3V TYPE 8-BIT 36CH SELECTOR SW BUILT-IN D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
The M62370GP is a CMOS semiconductor IC,containing 36 channels of 8-bit D-A converters.It is operable with a low supply voltage between 2.7~3.6V,and is easy to use due to serial data input,and 3-pin(DI,CLK,LD)connection with microcomputer.The IC also contains Do pin terminal,enabling cascade connection,and therefore is suitable for automatic control in combination with a microcomputer.

Function Serial data input terminal to input 16-bit long ssrial data Terminal to output MSB data of 16-bit shift register
Shift clock input terminal.Input signal at DI pin is input to 16-bit shift register at rise of shift clock pulse
When H-level signal is input to this terminal,the value stored in 16-bit shift register is loaded in decoder and D-A converter output register
8-bit D-A converter output terminal
