MM74C901 • MM74C902 Hex Inverting TTL Buffer • Hex Non-Inverting TTL Buffer
General Description
The MM74C901 and MM74C902 hex buffers employ complementary MOS to achieve wide supply operating range, low power consumption, and high noise immunity. These buffers provide direct interface from PMOS into CMOS or TTL and direct interface from CMOS to TTL or CMOS operating at a reduced VCC supply.
Features
s Wide supply voltage range: s Guaranteed noise margin: s High noise immunity: 3.0V to 15V 1.0V 0.45 VCC (typ.)
s TTL compatibility: Fan out of 2 driving standard TTL

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.
