The 74LVX125MX from onsemi (formerly Fairchild) is a low-voltage quad bus buffer with 3-state outputs in a 14-pin SOIC package. Operating from 2V to 3.6V with 5V-tolerant inputs, it provides four non-inverting buffer channels with independent output enables, ideal for interfacing 5V and 3V logic systems.<\/p>\n

It features four independent non-inverting buffer channels, each with its own output enable (active-high to disable). The inputs tolerate voltages up to 7V, allowing direct interfacing of 5V systems to 3V systems. With a typical propagation delay of 4.4 ns at 3.3V and a maximum quiescent current of just 4 \u00b5A, it is well-suited for mixed-voltage, low-power designs.","working_principle":"The 74LVX125MX comprises four identical non-inverting buffer channels with independent 3-state output control: (1) Input Stage: Each channel features a 5V-tolerant input that can accept signals above the supply voltage, enabling safe interface with higher-voltage logic families. Power-down protection circuitry prevents damaging current flow when the device is unpowered. (2) Buffer Stage: The LVX CMOS technology provides fast propagation (4.4ns typical at 3.3V) while maintaining low static power (4\u00b5A max). (3) Output Stage: Each channel has an independent active-high output enable. When the OE pin is HIGH, the output enters a high-impedance state, disconnecting it from the bus.","pin_description":"
