74LVTH125DB中文资料3.3 V quad buffer; 3-state数据手册Nexperia规格书

描述 Description

The 74LVT125; 74LVTH125 is a high-performance BiCMOS product designed for VCC operation at 3.3 V.
This device combines low static and dynamic power dissipation with high speed and high output drive. The 74LVT125; 74LVTH125 device is a quad buffer that is ideal for driving bus lines. The device features four output enable inputs (1OE, 2OE, 3OEand 4OE), each controlling one of the 3-state outputs.
