Texas Instruments Buffers, Drivers, Receivers, Transceivers CD54HC646F3A

The CD54HC646F3A is an octal bus transceiver and register with 3-state outputs, designed for multiplexed transmission of data. It operates with a supply voltage range of 2V to 6V and supports a wide temperature range from -55¬8C to 125¬8C. This device features independent registers for both A and B buses, allowing for real-time and stored data multiplexing. The output-enable (OE) and direction-control (DIR) inputs facilitate various transceiver functions, enabling data transfer between the two buses while maintaining high-impedance states during power transitions. The CD54HC646F3A is compatible with TTL voltage levels and can drive up to 15 LS-TTL loads, offering significant power reduction compared to traditional LS-TTL logic ICs. This product is suitable for applications requiring reliable data management and efficient power usage in harsh environments.
