MM74C906 * MM74C907 Hex Open Drain N-Channel Buffers * Hex Open Drain P-Channel Buffers
October 1987 Revised January 1999
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 driving 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 resistors. All inputs are protected from static discharge by diode clamps to VCC and to ground.
Features
s Wide supply voltage range: s Guaranteed noise margin: s High noise immunity: 3V to 15V 1V 0.45 VCC (typ.)
s High current sourcing and sinking open drain outputs

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