Product Overview
The Texas Instruments SN74ALS541N is an 8-channel non-inverting octal buffer and line driver designed with 3-state outputs in a 20-pin dual in-line package (PDIP). Built on Advanced Low-Power Schottky logic, it features a flow-through pinout architecture where data inputs sit directly opposite the corresponding outputs, simplifying board layout and bus routing.
Key Features
- Octal (8-channel) non-inverting line driver and buffer configuration
- 3-state bus-driving outputs with dual active-low output enable inputs
- Advanced Low-Power Schottky (ALS) logic family architecture
- Supply voltage operating range: 4.5 V to 5.5 V (5.0 V nominal)
- Output drive capability: 24 mA low-level (IOL), -15 mA high-level (IOH)
- Standard DIP-20 package with 0.1-inch (2.54 mm) lead spacing
- Flow-through architecture to reduce signal cross-talk on printed circuit boards
Applications
- Replacing damaged bus drivers in vintage computing boards and legacy industrial controllers
- Interfacing 5V logic buses with breadboard prototypes and DIY retro-computing designs
- Driving memory address lines or high-capacitance bus lines in microprocessor systems
Frequently Asked Questions
What is the pin arrangement on the SN74ALS541N?
This IC utilizes a flow-through pinout where all inputs reside on pins 2 through 9 and the matching non-inverting outputs are on pins 18 through 11. Output enables are located on pins 1 and 19.
What operating voltage does this logic IC require?
It operates on a standard 5.0 V DC power supply, with a functional range between 4.5 V and 5.5 V.
Why choose an individually pulled, verified chip instead of buying a mystery grab bag?
You receive the exact Texas Instruments chip photographed, marked clearly with intact pins and legible markings, saving you the hassle of sorting through bulk unverified lots. Standard orders ship at an $8 flat rate, qualify for free shipping at $28 or more, and leave our Idaho warehouse the same or next business day.
Clean vintage logic that drops right into your breadboard or repair socket without fighting modern knockoffs.
