Texas Instruments Logic - Buffers, Drivers, Receivers, Transceivers SN74BCT646DWE4

The SN74BCT646DWE4 is an octal bus transceiver and register with 3-state outputs, designed using state-of-the-art BiCMOS technology, which significantly reduces ICCZ. It features independent registers and enables for both A and B buses, allowing for multiplexed real-time and stored data transmission. The device includes output-enable (OE) and direction-control (DIR) inputs to manage transceiver functions effectively. Data on either the A or B bus can be clocked into the registers on the low-to-high transition of the respective clock inputs (CLKAB or CLKBA). The device supports high-impedance states during power-up or power-down, ensuring reliable operation. ESD protection exceeds JESD 22 standards, with ratings of 2000-V for the Human-Body Model and 200-V for the Machine Model. This product is suitable for applications requiring efficient data management between buses, making it a viable option for engineers looking for reliable bus transceivers and registers.
