SN74AHC08DR 2-input positive-AND gate ic
The SN74AHC08DR is a quadruple 2-input positive-AND gate integrated circuit from Texas Instruments, belonging to the widely adopted AHC (Advanced High-Speed CMOS) logic family. Designed to operate across a voltage range of 2 V to 5.5 V, it provides a versatile building block for digital logic circuits, offering a balanced performance profile of higher speed and lower power consumption compared to standard HC/HCT families. This device contains four independent AND gates, each performing the Boolean logic function Y = A • B. It is optimized for interfacing with slower HC/HCT logic or driving higher capacitive loads while maintaining excellent noise immunity, making it a reliable and fundamental component in a vast array of digital system designs from simple glue logic to complex control circuitry.
Each of the four gates features typical propagation delays of 7.5 ns at 5 V, delivering a significant speed improvement over basic HC logic. The device offers a balanced output drive capability of ±8 mA at 5 V, allowing it to effectively drive multiple inputs or moderate loads. It maintains CMOS-level low power consumption with a typical static current of just a few microamperes and features inputs that are compatible with TTL voltage levels when operated at 5 V. The chip is characterized for reliable performance in both commercial and industrial environments, featuring robust ESD protection on all pins.
