The is a Transistor-Transistor Logic (TTL) integrated circuit that functions as a Dual 2-Wide 2-Input AND-OR-INVERT (AOI) gate . It is commonly used in digital logic design to implement complex Boolean functions with a single chip. Key Features
: Operates at standard TTL voltage levels, typically requiring a 5V supply ( VCCcap V sub cap C cap C end-sub ) .
: It contains two separate AOI gates. Each gate takes two pairs of inputs, performs an AND operation on each pair, ORs the results together, and then inverts the final output.
: Typically available in a 14-pin Dual In-line Package (DIP) .
: A unique feature of the 7450 is that one of the two gates is expandable . This allows users to add more AND-gate inputs to the OR-gate section using external expansion components like the 7460.
: Common versions include the standard SN7450, the high-speed
: Specific pins are designated for connecting to an expander IC to increase input capacity. POST OFFICE BOX 655303 - Texas Instruments
