MM74C906 MM74C907
Hex Open Drain N-Channel Buffers
Hex Open Drain P-Channel Buffers
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 driv-
ing six P-channel devices. The open drain feature of these
buffers makes level shifting or wire AND and wire OR func-
tions by just the addition of pull-up or pull-down resistors.
All inputs are protected from static discharge by diode
clamps to V
CC
and to ground.

Absolute Maximum Ratings
(Note 1)
Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed. Except for "Operating Tempera-
ture Range" they are not meant to imply that the devices should be oper-
ated at these limits. The table of "Electrical Characteristics" provides
conditions for actual device operation.
