Introducción del producto:74LVC125APW Presentación del producto

The Nexperia 74LVC125APW is a quad non-inverting buffer/line driver with 3-state outputs in a TSSOP14 package. The device consists of four independent buffers with individual active LOW output enable inputs (nOE). A HIGH on nOE causes the corresponding output to assume a high-impedance OFF-state. Inputs can be driven from either 3.3V or 5V devices, enabling use as a translator in mixed-voltage environments. Schmitt-trigger action at all inputs provides tolerance to slower input rise and fall times. The Ioff circuitry disables outputs when the device is powered down, preventing damaging backflow current — essential for partial power-down applications. The device operates from 1.2V to 3.6V with ±24 mA output drive and is specified from -40°C to +125°C.

Principio de funcionamiento:74LVC125APW Principio de funcionamiento

The 74LVC125APW contains four independent non-inverting buffers, each with a dedicated active LOW output enable (nOE) input. When nOE is LOW, the buffer passes the input signal (nA) directly to the output (nY) with a propagation delay. When nOE is HIGH, the output enters a high-impedance (3-state) state, effectively disconnecting the buffer from the bus. This allows multiple devices to share a common bus without contention. The Schmitt-trigger input buffers provide hysteresis for noise immunity and slow-edge tolerance. The 5V tolerant inputs and outputs accept voltages up to 5.5V regardless of VCC, enabling level translation. The Ioff circuitry ensures that when VCC is at 0V, all outputs are high-impedance, preventing backflow current through the device.
