概要

Description

The SN74LVC125ABQAR is a Texas Instruments quad buffer/driver with 3-state outputs. It contains four noninverting buffers, each with its own active-low enable input. When an enable is low, the corresponding output follows the input; when the enable is high, that output goes high-impedance. It operates from an I/O supply of 1.65 to 3.6 V and accepts CMOS inputs within that range. It’s used to buffer or isolate digital signals on buses or between voltage domains, and to enable/disable signals for shared-lines without data loss. The ABQAR suffix indicates packaging and handling details (TI-specific): RoHS-compliant, Tape-and-Reel packaging, with the device available in a 14-pin package variant. For exact electrical characteristics, timing, and pinout, refer to the TI datasheet.

Features

SN74LVC125ABQAR features:
- Quad buffer/line driver with 3-state outputs
- Four noninverting buffers: A1→Y1, A2→Y2, A3→Y3, A4→Y4
- Independent output-enable inputs (OE1–OE4) for each buffer
- Ioff (partial-power-down) support for no back-powering when Vcc is 0
- Wide operating supply: Vcc = 1.65 V to 3.6 V (suitable for 3.3-V systems)
- CMOS/TTL-compatible inputs with standard logic thresholds
- Fast CMOS performance with low static current
- ESD protection on inputs/outputs
- Pb-free, RoHS-compliant packaging (e.g., 14-pin small-outline or similar; available in Tape & Reel)

Package

14-pin Small Outline Integrated Circuit (SOIC-14) package.

Pinout

- Pin count: 14 pins
- Function: Quad buffer/line driver with 3-state outputs (four non-inverting buffers). Each buffer has its own input, output, and an enable input (G1–G4). When the enable is high, the output follows the input; when low, the output is high-impedance. Operates as low-voltage CMOS (LVC) device.

Manufacturer

Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits (ICs) and related semiconductor products.

Application

Key application areas:
- High-speed buffering and fan-out for microcontrollers, FPGAs/ASICs.
- 3-state bus drivers for shared data/address buses (memory interfaces, backplanes, peripherals).
- Level shifting between different logic-voltage domains in mixed-signal systems.
- Signal isolation/conditioning to protect devices and reduce loading.
- Driving moderate-capacitance loads and improving edge rates in digital circuits.

Equivalent

Equivalent parts (same 4‑bit noninverting buffer with 3‑state outputs) from other vendors:
- Nexperia 74LVC125A (formerly NXP)
- STMicroelectronics 74LVC125A
- Renesas uPD74LVC125A (uPD74LVC125)
