General Description
The MM74C906 and MM74C907 buffers employ monolithic
CMOS technology in achieving open drain outputs. The
MM74C906 consists of six inverters driving six N -channel
devices; and the MM74C907 consists of six inverters dr iving six P-channel devices. The open drain feature of these
buffers makes level shifting or wire AND and wire OR functions by just the addition of pull-up or pull-down re sistors.
All inputs are protected from static discharge by diode
clamps to V
and to ground.
