SN74ALS646A-1NTG4

The SN74ALS646A-1NTG4 is an Integrated Circuit (IC) component manufactured by Texas Instruments. It is a octal bus transceiver with 3-state outputs designed for asynchronous two-way communication between data buses. Here are some key features and an overview of this IC component: 1. Octal Bus Transceiver: The SN74ALS646A-1NTG4 has eight bidirectional bus transceivers, making it suitable for data transfer between two independent buses. 2. 3-State Outputs: The IC has three-state outputs, allowing the bus lines to be effectively disconnected from the system when they are not actively transmitting or receiving data. 3. Voltage Compatibility: The IC is designed to operate with a wide range of voltage supply levels, from 4.5V to 5.5V, making it suitable for various electronic systems and applications. 4. TTL Compatibility: The SN74ALS646A-1NTG4 is compatible with TTL (Transistor-Transistor Logic) inputs, enabling easy integration with existing TTL-based systems without any additional level shifting circuitry. 5. Direction-Controlled Inputs: This IC has direction-controlled inputs (DIR) that determine the data flow direction between the A and B buses. By setting the DIR pin high or low, the data can be transmitted either from bus A to bus B or vice versa
