Revised January 2004 MM74C32 Quad 2-Input OR Gate General Description Features The MM74C32 employs complementary MOS (CMOS) transistors to achieve low power and high noise margin, these gates provide the basic functions used in the implementation of digital integrated circuit systems. The N- and P-channel enhancement mode transistors provide a symmetrical circuit with output swings essentially equal to the supply voltage. This results in high noise immunity over a wide supply voltage range. No DC power other than that caused by leakage current is consumed during static conditions. All inputs are protected against static discharge damage. ■ Wide supply voltage range: 3.0V to 15V ■ Guaranteed noise margin: 1.0V ■ High noise immunity: 0.45V VCC (typ.) ■ Low power TTL compatibility: fan out of 2 driving 74L Ordering Code: Order Number MM74C32N Package Number N14A Package Description 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Top View © 2004 Fairchild Semiconductor Corporation DS005881 www.fairchildsemi.com MM74C32 Quad 2-Input OR Gate October 1987 MM74C32 Absolute Maximum Ratings(Note 1) Lead Temperature −0.3V to VCC + 0.3V Voltage at Any Pin Operating Temperature Range −55°C to +125°C Storage Temperature Range −65°C to +150°C 700 mW Small Outline 500 mW Operating VCC Range 260°C (Soldering, 10 seconds) Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
