Revised January 1999 MM74C901 • MM74C902 Hex Inverting TTL Buffer • Hex Non-Inverting TTL Buffer General Description Features 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. ■ Wide supply voltage range: ■ Guaranteed noise margin: ■ High noise immunity: 3.0V to 15V 1.0V 0.45 VCC (typ.) ■ TTL compatibility: Fan out of 2 driving standard TTL Ordering Code: Order Number MM74C901M Package Number Package Description M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150” Narrow MM74C901N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-011, 0.300” Wide MM74C902M M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150” Narrow MM74C902N N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-011, 0.300” Wide Devices also available in Tape and Reel.
