概述

Description

74LCX125FT is a quad buffer with 3-state outputs from the 74LCX CMOS family (low power, high speed). It’s used to buffer data lines and to allow bus sharing by tri-stating outputs when not needed.
Key points:
- Four independent buffers: A1–A4 inputs; Y1–Y4 outputs; one enable per buffer.
- Output enable control: when the corresponding enable is active, the output follows the input; when not, the output is high-impedance.
- Supply and compatibility: typically operates from 3.0 to 5.5 V and is CMOS/TTL input compatible.
- Packaging: “FT” denotes a specific packaging/lead configuration variant for this part.
- Applications: data buffering between devices, level shifting, bus isolation, and interfacing microcontrollers to memory or peripherals.
Note: Check the exact datasheet for pinout (A, Y, OE pins), drive capability, propagation delay, and voltage ranges for your specific package.

Features

74LCX125FT features:
- Quad buffer/line driver with 3-state (tri-state) outputs
- Four independent non-inverting buffers
- Separate active-low output-enable inputs (OE1–OE4)
- Outputs go high-impedance when disabled for bus sharing
- Low-power CMOS LCX technology
- Wide operating voltage: typically 2.0 V to 3.6 V
- CMOS/TTL–compatible input thresholds
- Fast switching/low propagation delay
- Available in standard 14-pin packages (e.g., DIP/SOIC)

Package

14-pin surface-mount package (SOIC-14). The FT suffix denotes the specific package variant (lead-free). Check the datasheet for the exact package code.

Pinout

- Pin count: 14 pins (14‑pin package such as SOIC/DIP)
- Function: Quad buffer/line driver with 3‑state outputs (four buffers). Each buffer has an input (A1–A4), an output (Y1–Y4), and an active‑low enable (1OE–4OE). When the corresponding OE is LOW, Y follows A; when OE is HIGH, Y is high‑impedance. Non-inverting.

Manufacturer

Manufacturer: Nexperia (formerly Philips Semiconductors/NXP).
What kind of company: A Dutch multinational semiconductor company that designs and manufactures discrete devices, logic ICs, and related semiconductor components for electronics.

Application

74LCX125FT is a quad buffer with 3-state outputs. Common applications:
- Buffering/isolating microcontroller/microprocessor data and address buses.
- Tri-state bus gating to prevent contention when multiple devices share lines.
- Demultiplexing an address/data bus in memory/IO interfaces.
- Driving long lines, backplanes, or LCDs with controlled fan-out.
- Level-safe interfacing between compatible logic-voltage domains.
- General-purpose buffering to protect sources and reduce loading.

Equivalent

Equivalent devices (quad buffer with 3-state outputs) from other families include:
- 74HC125
- 74HCT125
- 74LS125
- 74ACT125
- 74LVC125
Note: Voltage ranges/thresholds differ. Choose a part that matches your supply (e.g., 2–3.3 V for LVC/LVX, 4.5–5 V for HC/LS/ACT).
