Module 2: 8-bit D-A output pin (y side)
Module 1: Reference voltage input pin
Module 2: Reference voltage input pin
Power supply (VCC) pin
Reset pin
When input level is changed from
H
to
L
, D-A output becomes 0 V (D-
A data: 00h), and MON output becomes VREF
×
255/256 (MON data:
FFh). Even if input level is restored from
L
to
H
, output is maintained
until next data setting. TTL-based.

At rising edge of input signal from
L
to
H
, data in 16-bit shift register is loaded
into D/A data register. TTL-based.
