Overview
The SN74LVTH125PWG4, produced by Texas Instruments, is a quad buffer/line driver with 3-state outputs. This device is designed for low-voltage operation, specifically at 3.3 V, but it also supports mixed-mode signal operation, allowing it to interface with 5-V system environments. It features independent line drivers, each with 3-state outputs controlled by the output-enable (OE) inputs. The device is fully specified for hot-insertion applications and supports partial power-down mode operation.
