MM54C901/MM74C901 Hex Inverting TTL Buffer
MM54C902/MM74C902 Hex Non-Inverting TTL Buffer
MM54C903/MM74C903 Hex Inverting CMOS Buffer
MM54C904/MM74C904 Hex Non-Inverting CMOS Buffer
General Description
These 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 V
CC
supply.
