Description

SN74LS126ADR is a Texas Instruments part in the 74LS TTL family: a quad buffer/driver with 3-state outputs. Key points:
- Four noninverting buffers (inputs A1–A4; outputs Y1–Y4).
- Each buffer has its own output-enable input (OE1–OE4). When enabled, the input is passed to the output; when disabled, the output goes high-impedance.
- Used to buffer signals and to allow multiple devices to share a common bus.
- Operates from a 5 V supply (typical 4.75–5.25 V) with TTL-compatible input levels.
- ADR suffix indicates a specific packaging option (surface-mount, lead-free/RoHS-compliant) from TI; check the datasheet for exact package details.
Common uses: bus driving, level buffering between devices, and interfaces where tri-state outputs are needed.

Package

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

Pinout

- Pin count: 14 pins (DIP/SMD package variants)
- Function: SN74LS126ADR is a Quad buffer/line driver with 3-state outputs. It has four data inputs (A1–A4) and four outputs (Y1–Y4); outputs can be tri-stated via an enable input (controls all four buffers). Operates from 5V TTL logic.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational corporation that designs and manufactures semiconductors and integrated circuits (analog and digital ICs) and related electronics.

Application

SN74LS126ADR is a quad buffer/line driver with 3-state outputs. Applications:
- Tri-state bus drivers for shared data/address lines
- Microprocessor/microcontroller data and address bus interfacing and buffering
- Memory interface buffering (RAM/ROM)
- Signal isolation between logic blocks and different supply domains
- General-purpose buffering where high-impedance state is required to release a bus
(Uses: bus sharing, isolation, and controlled data flow in TTL/CMOS digital systems.)

Equivalent

Equivalents (same function, 4‑bit 3‑state buffer, TTL 74LS126): MC74LS126 (Motorola/ON Semiconductor), MM74LS126 (National Semiconductor), AM74LS126 (AMD), TC74LS126 (Toshiba). Other brands label as SN74LS126N/74LS126. CMOS alternatives (not identical but similar): 74HC126 and 74HCT126.
