Texas Instruments Logic - Buffers, Drivers, Receivers, Transceivers SN74LVTH126D

The SN74LVTH126D is a low-voltage buffer designed for operation with a supply voltage of 3.3 V, while also supporting mixed-mode signal operation with 5-V input and output voltages. It features independent line drivers with 3-state outputs, allowing each output to enter a high-impedance state when the associated output-enable (OE) input is low. The device includes active bus-hold circuitry that maintains valid logic levels on unused or undriven inputs, eliminating the need for external pull-up or pull-down resistors. This buffer is suitable for hot-insertion applications, as it incorporates Ioff and power-up 3-state support to prevent damaging current backflow during power transitions. The device is rated for latch-up performance exceeding 100 mA per JESD 78, Class II, and offers robust ESD protection, exceeding the requirements of various models. The operating temperature range is from -40¬8C to 85¬8C, making it versatile for different environmental conditions. Engineers considering this product should note its specifications for output drive capabilities, with a maximum output current of 64 mA in the low state, and its compatibility with both 3.3 V and 5 V systems, which may be beneficial for mixed-voltage applications.
