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 P MOS into CMOS or
TTL and direct interface from CMOS to TTL or CMOS
operating at a reduced V
CC
supply.
Features
■ Wide supply voltage range: 3.0V to 15V
■ Guaranteed noise margin: 1.0V
■ High noise immunity: 0.45 V
CC
(typ.)
■ TTL compatibility: Fan out of 2 driving standard TTL
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to t he ordering code.

Absolute Maximum Ratings(Note 1)
Note 1: “Absolute Maxi mum Ratings” are those valu es beyond which the
safety of the device cannot be guaranteed. Ex ce pt for “O perating Temperature Range” they are not mean t to imply that the devices sho uld be operated at these limits. The table of “Electrical Characteristics” provides
conditions for actual device op eration.
