Overview
('t) ~ ~National -c~ ~ Semiconductor ~ N o~ DAC1242/DAC1243 Process Control DACs cThe DAC1242 is a current-sinking device, while the DAC1243 provides true current sourcing into a ground referenced load.
The digital input registers are similar to an INS8255, allowing direct TTL interfacing to a variety of 8-bit microprocessors (8080, 8085, 8048, 8070, 8073, NSC800, Z80, et al).
Interfacing to other microprocessor families or larger computers requires only 1 or 2 TTL packages.
The device occupies 4 contiguous bytes of I/O or address space.
