Overview
The 74LVT125D/AUJ, produced by NXP USA Inc., is a quad buffer/line driver with 3-state outputs. This device is designed for low-voltage (3.3 V) VCC operation and is capable of providing a TTL interface to a 5-V system environment. It features independent line drivers with 3-state outputs controlled by the output enable inputs (nOE). The device is fully specified for partial power-down applications and includes bus-hold data inputs to eliminate the need for external pull-up resistors.
