Visão Geral
Description
SN74LVC125ABQAR is TI’s quad buffer/driver with 3-state outputs (four non-inverting buffers). Each buffer has an input (A), output (Y), and its own 3-state enable input. When the enable is active, Y follows A; when disabled, Y is high-impedance, allowing buses to be shared.
Key points:
- Part of the LVC family: operates from 1.65 to 3.6 V, CMOS logic, TTL-compatible inputs.
- 4 independent buffers with 3-state outputs.
- Fast propagation with typical drive suitable for interfacing microcontrollers, FPGAs, and memory.
- ABI suffix ABQAR indicates RoHS-compliant packaging with tape-and-reel delivery (typical 14-pin packages like SOIC/TSSOP variants, depending on order).
Typical uses: buffering signals between devices at the same or different voltage domains, level shifting, and bus interfacing where multiple outputs may need to share a line.

Application
SN74LVC125ABQAR is a 4‑bit buffer/line driver with 3‑state outputs.
Common applications:
- Buffering data/address buses between CPUs, memories, FPGAs, and peripherals to reduce fan‑out.
- Tri‑state bus sharing and device isolation during power‑down or multi‑device contention (OE controls enables).
- Level shifting and buffer driving for low‑voltage logic domains in 1.65–3.6 V systems.
- I/O expansion and interface for microcontrollers, DSPs, sensors, ADCs/DACs, and memory devices.
- High‑speed digital signal buffering on PCBs and backplanes where short‑to‑mid length traces need clean drive.
