Texas Instruments Logic - Logic - Buffers, Drivers, Receivers, Transceivers - SN74LVTH646DWRG4 SN74LVTH646DWRG4

The SN74LVTH646DWRG4 is a low-voltage bus transceiver designed for 3.3-V operation while providing compatibility with 5-V systems. It supports mixed-mode signal operation, allowing for 5-V input and output voltages. The device features a typical output ground bounce (VOLP) of less than 0.8 V at 3.3 V and is capable of operating down to 2.7 V, making it suitable for unregulated battery applications. This transceiver includes bus hold circuitry to maintain valid logic levels on unused inputs, eliminating the need for external pull-up or pull-down resistors. It is fully specified for hot-insertion applications, with Ioff and power-up 3-state support to prevent backflow current during power transitions. The device operates with a temperature range of -40¬8C to 85¬8C and is available in various package types, including SOIC and TSSOP. Engineers should consider this product for applications requiring reliable data transmission between different voltage systems, particularly in environments where space and power efficiency are critical. However, it is important to note that this part is marked as obsolete.
