Texas Instruments Integrated Circuits (ICs) - Logic - Buffers, Drivers, Receivers, Transceivers SN74LVTH2952DGVR

The SN74LVTH2952DGVR is an octal bus transceiver designed for low-voltage (3.3 V) operation while providing compatibility with 5 V systems. It features two 8-bit back-to-back registers that facilitate bidirectional data flow between two buses, with data being stored on the rising edge of the clock input. The device supports mixed-mode signal operation, allowing for 5 V input and output voltages. This transceiver includes active bus-hold circuitry, which maintains valid logic levels on unused or floating data inputs, eliminating the need for external pull-up or pull-down resistors. It is specified for hot-insertion applications, with Ioff and power-up 3-state support to prevent damaging current backflow during power transitions. The device operates within a temperature range of -40¬8C to 85¬8C and is available in a 24-pin TVSOP package. Engineers considering this product should note its typical output ground bounce of less than 0.8 V at 3.3 V and its robust ESD protection, exceeding 2000 V for the human-body model.
